Adding a Connection to Amazon Redshift

To add a connection to Amazon Redshift:

1. In the application console, navigate to the Connections page.
2. At the Add Connections panel, select the icon for the connection you want to add.
3. If the Amazon Redshift icon is not available, click the Add More icon to download and install the Amazon Redshift connector from the CData site.

For required properties, see the Settings tab.

For connection properties that are not typically required, see the Advanced tab.

Connecting to Amazon Redshift

The following connection properties are usually required to connect to Amazon Redshift.

• Server: The host name or IP of the server hosting the Amazon Redshift database.
• Database: The database that you created for your Amazon Redshift cluster.
• Port (optional): The port of the server hosting the Amazon Redshift database. 5439 by default.

Follow these steps to obtain these values in the AWS Management Console:

1. Open the Amazon Redshift console (http://console.aws.amazon.com/redshift).
2. On the Clusters page, click the name of the cluster.
3. On the Configuration tab, obtain the properties from the "Cluster Database Properties" section. The connection property values are the same as the values set in the ODBC URL.

The Sync App provides secure communication with Amazon Redshift server using SSL encryption. You can optionally turn off SSL encryption by setting UseSSL to false.

You can also leverage SSL authentication to connect to Amazon Redshift data. To do so, specify the following connection properties:

• SSLClientCert: The name of the certificate store for the client certificate. This is used in the case of 2-way SSL, where truststore and keystore are kept on both the client and server machines.
• SSLClientCertPassword: If a client certificate store is password-protected, set this value to the store's password.
• SSLClientCertSubject: The subject of the TLS/SSL client certificate. This is used to locate the certificate in the store.
• SSLClientCertType: The certificate type of the client store.
• SSLServerCert: The certificate to be accepted from the server.

Example connection string (standard user and password pair and inactive SSL encryption):

User=username;Password=password;Server=example.us-west-2.redshift.amazonaws.com;Database=your_database;UseSSL=false;"

Authenticating to Amazon Redshift

CData Sync App supports authentication via standard credentials, IAM credentials, ADFS, Ping Federate, Microsoft Entra ID (Azure AD), or Azure AD PKCE.

Standard Authentication

To connect to Amazon Redshift with login credentials, set these properties:

• AuthScheme: Basic.
• User: The authenticating user's login.
• Password: The authenticating user's password.

Example connection string:

AuthScheme=Basic;User=user;Password=password;Server=example.us-west-2.redshift.amazonaws.com;Database=your_database;

IAM Credentials

Set the AuthScheme to IAMCredentials.

Example connection string:

AuthScheme=IAMCredentials;Server=example.us-west-2.redshift.amazonaws.com;Database=your_database;User=your_user;AWSAccessKey=your_access_key;AWSSecretKey=your_secretkey;

If you are connecting using an IAM role with temporary credentials you are also required to apply AWSSessionToken.

You can optionally apply:

• AutoCreate: Create a database user with the name specified for User if one does not exist while connecting.
• DbGroups: Database groups the database user joins for the current session.

ADFS

To connect to ADFS, set these properties:

• AuthScheme: ADFS.
• User: The authenticating ADFS user.
• Password: The password of the authenticating ADFS user.
• SSOLoginURL: The SSO provider's login URL.

Example connection string:

AuthScheme=ADFS;User=username;Password=password;SSOLoginURL='https://sts.company.com';

ADFS Integrated

The ADFS Integrated flow indicates you are connecting with the user credentials of the currently logged in Windows user. To use the ADFS Integrated flow, do not specify the User and Password, but otherwise follow the same steps noted above under ADFS.

PingFederate

To connect to PingFederate, set these properties:

• AuthScheme: PingFederate.
• User: The authenticating PingFederate user.
• Password: The authenticating user's PingFederate password.
• SSOLoginURL: The SSO provider's login URL.
• AWSRoleARN (optional): If you have multiple role ARNs, specify the one you want to use for authorization.
• AWSPrincipalARN (optional): If you have multiple principal ARNs, specify the one you want to use for authorization.
• SSOProperties (optional): If you want to include your username and password as an authorization header in requests to Amazon S3, set this to Authscheme=Basic.

To enable mutual SSL authentication for SSOLoginURL, the WS-Trust STS endpoint, configure these SSOProperties:

• SSLClientCert
• SSLClientCertType
• SSLClientCertSubject
• SSLClientCertPassword

Example connection string:

Server=redshift-cluster-1.xxxxxxxxxxxx.us-east-1.redshift.amazonaws.com;Database=dev;Port=5439;UseSSL=true;SSLServerCert=*;AuthScheme=PingFederate;AutoCreate=TRUE;SSOLoginURL=https://mycustomserver.com:9033/idp/sts.wst;SSOExchangeUrl=https://us-east-1.signin.aws.amazon.com/platform/saml/acs/764ef411-xxxxxx;User=admin;Password=PassValue;AWSRegion=NORTHERNVIRGINIA;

This section details a selection of advanced features of the Amazon Redshift Sync App.

SSL Configuration

Use SSL Configuration to adjust how Sync App handles TLS/SSL certificate negotiations. You can choose from various certificate formats;. For further information, see the SSLServerCert property under "Connection String Options" .

Firewall and Proxy

Configure the Sync App for compliance with Firewall and Proxy, including Windows proxies. You can also set up tunnel connections.

Logging

For an overview of configuration settings that can be used to refine CData logging, see Logging. Only two connection properties are required for basic logging, but there are numerous features that support more refined logging, which enables you to use the LogModules connection property to specify subsets of information to be logged.

Customizing the SSL Configuration

By default, the Sync App attempts to negotiate TLS with the server. The server certificate is validated against the default system trusted certificate store. You can override how the certificate gets validated using the SSLServerCert connection property.

To specify another certificate, see the SSLServerCert connection property.

Client SSL Certificates

The Amazon Redshift Sync App also supports setting client certificates. Set the following to connect using a client certificate.

• SSLClientCert: The name of the certificate store for the client certificate.
• SSLClientCertType: The type of key store containing the TLS/SSL client certificate.
• SSLClientCertPassword: The password for the TLS/SSL client certificate.
• SSLClientCertSubject: The subject of the TLS/SSL client certificate.

Connecting Through a Firewall or Proxy

Set the following properties:

• To use a proxy-based firewall, set FirewallType, FirewallServer, and FirewallPort.
• To tunnel the connection, set FirewallType to TUNNEL.
• To authenticate, specify FirewallUser and FirewallPassword.
• To authenticate to a SOCKS proxy, additionally set FirewallType to SOCKS5.

Tables	Optional setting that restricts the tables reported to a subset of all available tables. For example, Tables=TableA,TableB,TableC .
Views	Optional setting that restricts the views reported to a subset of the available tables. For example, Views=ViewA,ViewB,ViewC .
IgnoredSchemas	Visibility restriction filter which is used to hide the list of schemas by metadata quering. For example, 'information_schema, pg_catalog'. Schema names are case sensitive.

Miscellaneous

---

Property	Description
AllowPreparedStatement	Prepare a query statement before its execution.
FetchResultSetMetadata	This field sets whether the provider retrieves metadata pertaining to the schema and table name for resultset columns returned by the server.
IncludeTableTypes	If set to true, the provider will query for the types of individual tables and views.
InsertMode	Specifies what method to use when inserting bulk data. By default DML mode is used.
IsServerless	The provider cannot detect endpoint to connect, if you are using a custom domain names for connections. Set this property to True when you are connecting to the Amazon Redshift serverless instance, as well specify the property AWSRegion in this case.
LZ4Compression	When set the driver notifies the server to compress data packets with lz4 compression algorithm.
MaxRows	Specifies the maximum number of rows returned for queries that do not include either aggregation or GROUP BY.
Other	Specifies advanced connection properties for specialized scenarios. Use this property only under the guidance of our Support team to address specific issues.
QueryPassthrough	This option passes the query to the Amazon Redshift server as is.
RedshiftToS3RoleARN	The Amazon Resource Name of the role to use when authenticating S3 with IAM role by the COPY command for the bulk inserts.
S3Bucket	Specifies the name of AWS S3 bucket to upload bulk data for staging.
S3BucketFolder	Specifies the name of the folder in AWS S3 bucket to upload bulk data for staging. By default bulk data are staged in the root folder.
StripOutNulls	When set the null characters are stripped out from character values in bulk operations.
Timeout	Specifies the maximum time, in seconds, that the provider waits for a server response before throwing a timeout error.
TimeZone	Set time zone for the current session.
UseUIDForStaging	Use this property in combination with InsertMode assigned with S3Staging or S3StagingWithIAM. By default the the driver creates staging files with names that prepend the targeted table's name, so the files are overwritten between sessions. When the property is set to True , the provider additionally attaches temporary unique identifiers to these names. It may be required if you use parallel jobs to insert rows into the same table. Thus, the staging files are not overwritten by the jobs. A caveat is that using this property adds to the number of staging files put onto S3 bucket, since the file names are not controlled by the driver between different sessions. In this case you may want to define an AWS S3 policy on the bucket to remove staging files that were stored in a bucket automatically.

Property	Description
AzureTenant	Identifies the Amazon Redshift tenant being used to access data. Accepts either the tenant's domain name (for example, contoso.onmicrosoft.com ) or its directory (tenant) ID.

Identifies the Amazon Redshift tenant being used to access data. Accepts either the tenant's domain name (for example, contoso.onmicrosoft.com ) or its directory (tenant) ID.

Remarks

A tenant is a digital container for your organization's users and resources, managed through Microsoft Entra ID (formerly Azure AD). Each tenant is associated with a unique directory ID, and often with a custom domain (for example, microsoft.com or contoso.onmicrosoft.com).

To find the directory (tenant) ID in the Microsoft Entra Admin Center, navigate to Microsoft Entra ID > Properties and copy the value labeled "Directory (tenant) ID".

This property is required in the following cases:

• When AuthScheme is set to AzureServicePrincipal or AzureServicePrincipalCert
• When AuthScheme is AzureAD and the user account belongs to multiple tenants

You can provide the tenant value in one of two formats:

• A domain name (for example, contoso.onmicrosoft.com)
• A directory (tenant) ID in GUID format (for example, c9d7b8e4-1234-4f90-bc1a-2a28e0f9e9e0)

Specifying the tenant explicitly ensures that the authentication request is routed to the correct directory, which is especially important when a user belongs to multiple tenants or when using service principal–based authentication.

If this value is omitted when required, authentication may fail or connect to the wrong tenant. This can result in errors such as unauthorized or resource not found.

This section provides a complete list of the SSO properties you can configure in the connection string for this provider.

Additional properties required to connect to the identity provider, formatted as a semicolon-separated list.

This is used with the SSOLoginURL.

SSO configuration is discussed further in .

The URL used for consuming the SAML response and exchanging it for service specific credentials.

Remarks

The CData Sync App will use the URL specified here to consume a SAML response and exchange it for service specific credentials. The retrieved credentials are the final piece during the SSO connection that are used to communicate with Amazon Redshift.

This section provides a complete list of the OAuth properties you can configure in the connection string for this provider.

---

Property	Description
OAuthClientId	Specifies the client ID (also known as the consumer key) assigned to your custom OAuth application. This ID is required to identify the application to the OAuth authorization server during authentication.
OAuthClientSecret	Specifies the client secret assigned to your custom OAuth application. This confidential value is used to authenticate the application to the OAuth authorization server. (Custom OAuth applications only.).
Scope	Specifies the scope of the authenticating user's access to the application, to ensure they get appropriate access to data. If a custom OAuth application is needed, this is generally specified at the time the application is created.

Specifies the client ID (also known as the consumer key) assigned to your custom OAuth application. This ID is required to identify the application to the OAuth authorization server during authentication.

Remarks

This property is required in two cases:

• When using a custom OAuth application, such as in web-based authentication flows, service-based authentication, or certificate-based flows that require application registration.
• If the driver does not provide embedded OAuth credentials.

(When the driver provides embedded OAuth credentials, this value may already be provided by the Sync App and thus not require manual entry.)

OAuthClientId is generally used alongside other OAuth-related properties such as OAuthClientSecret and OAuthSettingsLocation when configuring an authenticated connection.

OAuthClientId is one of the key connection parameters that need to be set before users can authenticate via OAuth. You can usually find this value in your identity provider’s application registration settings. Look for a field labeled Client ID, Application ID, or Consumer Key.

While the client ID is not considered a confidential value like a client secret, it is still part of your application's identity and should be handled carefully. Avoid exposing it in public repositories or shared configuration files.

For more information on how this property is used when configuring a connection, see Establishing a Connection.

Specifies the client secret assigned to your custom OAuth application. This confidential value is used to authenticate the application to the OAuth authorization server. (Custom OAuth applications only.).

Remarks

This property (sometimes called the application secret or consumer secret) is required when using a custom OAuth application in any flow that requires secure client authentication, such as web-based OAuth, service-based connections, or certificate-based authorization flows. It is not required when using an embedded OAuth application.

The client secret is used during the token exchange step of the OAuth flow, when the driver requests an access token from the authorization server. If this value is missing or incorrect, authentication fails with either an invalid_client or an unauthorized_client error.

OAuthClientSecret is one of the key connection parameters that need to be set before users can authenticate via OAuth. You can obtain this value from your identity provider when registering the OAuth application.

Notes:

• This value should be stored securely and never exposed in public repositories, scripts, or unsecured environments.
• Client secrets may also expire after a set period. Be sure to monitor expiration dates and rotate secrets as needed to maintain uninterrupted access.

For more information on how this property is used when configuring a connection, see Establishing a Connection

Specifies the scope of the authenticating user's access to the application, to ensure they get appropriate access to data. If a custom OAuth application is needed, this is generally specified at the time the application is created.

Remarks

Scopes are set to define what kind of access the authenticating user will have; for example, read, read and write, restricted access to sensitive information. System administrators can use scopes to selectively enable access by functionality or security clearance.

When InitiateOAuth is set to GETANDREFRESH, you must use this property if you want to change which scopes are requested.

When InitiateOAuth is set to either REFRESH or OFF, you can change which scopes are requested using either this property or the Scope input.

This section provides a complete list of the SSL properties you can configure in the connection string for this provider.

---

Property	Description
SSLClientCert	Specifies the TLS/SSL client certificate store for SSL Client Authentication (2-way SSL). This property works in conjunction with other SSL-related properties to establish a secure connection.
SSLClientCertType	Specifies the type of key store containing the TLS/SSL client certificate for SSL Client Authentication. Choose from a variety of key store formats depending on your platform and certificate source.
SSLClientCertPassword	Specifes the password required to access the TLS/SSL client certificate store. Use this property if the selected certificate store type requires a password for access.
SSLClientCertSubject	Specifes the subject of the TLS/SSL client certificate to locate it in the certificate store. Use a comma-separated list of distinguished name fields, such as CN=www.server.com, C=US. The wildcard * selects the first certificate in the store.
SSLServerCert	Specifies the certificate to be accepted from the server when connecting using TLS/SSL.

Specifies the TLS/SSL client certificate store for SSL Client Authentication (2-way SSL). This property works in conjunction with other SSL-related properties to establish a secure connection.

Remarks

This property specifies the client certificate store for SSL Client Authentication. Use this property alongside SSLClientCertType, which defines the type of the certificate store, and SSLClientCertPassword, which specifies the password for password-protected stores. When SSLClientCert is set and SSLClientCertSubject is configured, the driver searches for a certificate matching the specified subject.

Certificate store designations vary by platform. On Windows, certificate stores are identified by names such as MY (personal certificates), while in Java, the certificate store is typically a file containing certificates and optional private keys.

The following are designations of the most common User and Machine certificate stores in Windows:

MY	A certificate store holding personal certificates with their associated private keys.
CA	Certifying authority certificates.
ROOT	Root certificates.
SPC	Software publisher certificates.

For PFXFile types, set this property to the filename. For PFXBlob types, set this property to the binary contents of the file in PKCS12 format.

Specifies the type of key store containing the TLS/SSL client certificate for SSL Client Authentication. Choose from a variety of key store formats depending on your platform and certificate source.

Remarks

This property determines the format and location of the key store used to provide the client certificate. Supported values include platform-specific and universal key store formats. The available values and their usage are:

USER - default	For Windows, this specifies that the certificate store is a certificate store owned by the current user. Note that this store type is not available in Java.
MACHINE	For Windows, this specifies that the certificate store is a machine store. Note that this store type is not available in Java.
PFXFILE	The certificate store is the name of a PFX (PKCS12) file containing certificates.
PFXBLOB	The certificate store is a string (base-64-encoded) representing a certificate store in PFX (PKCS12) format.
JKSFILE	The certificate store is the name of a Java key store (JKS) file containing certificates. Note that this store type is only available in Java.
JKSBLOB	The certificate store is a string (base-64-encoded) representing a certificate store in JKS format. Note that this store type is only available in Java.
PEMKEY_FILE	The certificate store is the name of a PEM-encoded file that contains a private key and an optional certificate.
PEMKEY_BLOB	The certificate store is a string (base64-encoded) that contains a private key and an optional certificate.
PUBLIC_KEY_FILE	The certificate store is the name of a file that contains a PEM- or DER-encoded public key certificate.
PUBLIC_KEY_BLOB	The certificate store is a string (base-64-encoded) that contains a PEM- or DER-encoded public key certificate.
SSHPUBLIC_KEY_FILE	The certificate store is the name of a file that contains an SSH-style public key.
SSHPUBLIC_KEY_BLOB	The certificate store is a string (base-64-encoded) that contains an SSH-style public key.
P7BFILE	The certificate store is the name of a PKCS7 file containing certificates.

BCFKSFILE	The certificate store is the name of a file that contains an Bouncy Castle keystore.
BCFKSBLOB	The certificate store is a string (base-64-encoded) that contains a Bouncy Castle keystore.

Specifes the password required to access the TLS/SSL client certificate store. Use this property if the selected certificate store type requires a password for access.

Remarks

This property provides the password needed to open a password-protected certificate store. This property is necessary when using certificate stores that require a password for decryption, as is often recommended for PFX or JKS type stores.

If the certificate store type does not require a password, for example USER or MACHINE on Windows, this property can be left blank. Ensure that the password matches the one associated with the specified certificate store to avoid authentication errors.

Specifes the subject of the TLS/SSL client certificate to locate it in the certificate store. Use a comma-separated list of distinguished name fields, such as CN=www.server.com, C=US. The wildcard * selects the first certificate in the store.

Remarks

This property determines which client certificate to load based on its subject. The Sync App searches for a certificate that exactly matches the specified subject. If no exact match is found, the Sync App looks for certificates containing the value of the subject. If no match is found, no certificate is selected.

The subject should follow the standard format of a comma-separated list of distinguished name fields and values. For example, CN=www.server.com, OU=Test, C=US. Common fields include the following:

Field	Meaning
CN	Common Name. This is commonly a host name like www.server.com.
O	Organization
OU	Organizational Unit
L	Locality
S	State
C	Country
E	Email Address

Note: If any field contains special characters, such as commas, the value must be quoted. For example: CN="Example, Inc.", C=US.

Specifies the certificate to be accepted from the server when connecting using TLS/SSL.

Remarks

If you are using a TLS/SSL connection, use this property to specify the TLS/SSL certificate to be accepted from the server. If you specify a value for this property, all other certificates that are not trusted by the machine are rejected.

This property can take the following forms:

Description	Example
A full PEM Certificate (example shortened for brevity)	-----BEGIN CERTIFICATE----- MIIChTCCAe4CAQAwDQYJKoZIhv......Qw== -----END CERTIFICATE-----
A path to a local file containing the certificate	C:\cert.cer
The public key (example shortened for brevity)	-----BEGIN RSA PUBLIC KEY----- MIGfMA0GCSq......AQAB -----END RSA PUBLIC KEY-----
The MD5 Thumbprint (hex values can also be either space- or colon-separated)	ecadbdda5a1529c58a1e9e09828d70e4
The SHA1 Thumbprint (hex values can also be either space- or colon-separated)	34a929226ae0819f2ec14b4a3d904f801cbb150d

Note: It is possible to use '*' to signify that all certificates should be accepted, but due to security concerns this is not recommended.

Remarks

SSHClientCert must contain a valid private key in order to use public key authentication. A public key is optional, if one is not included then the Sync App generates it from the private key. The Sync App sends the public key to the server and the connection is allowed if the user has authorized the public key.

The SSHClientCertType field specifies the type of the key store specified by SSHClientCert. If the store is password protected, specify the password in SSHClientCertPassword.

Some types of key stores are containers which may include multiple keys. By default the Sync App will select the first key in the store, but you can specify a specific key using SSHClientCertSubject.

The password of the SSHClientCert key if it has one.

Remarks

This property is required for SSH tunneling when using certificate-based authentication. If the SSH certificate is in a password-protected key store, provide the password using this property to access the certificate.

The subject of the SSH client certificate.

Remarks

When loading a certificate the subject is used to locate the certificate in the store.

If an exact match is not found, the store is searched for subjects containing the value of the property.

If a match is still not found, the property is set to an empty string, and no certificate is selected.

The special value "*" picks the first certificate in the certificate store.

The certificate subject is a comma separated list of distinguished name fields and values. For instance "CN=www.server.com, OU=test, C=US, [email protected]". Common fields and their meanings are displayed below.

This section provides a complete list of the Firewall properties you can configure in the connection string for this provider.

---

Property	Description
FirewallType	Specifies the protocol the provider uses to tunnel traffic through a proxy-based firewall.
FirewallServer	Identifies the IP address, DNS name, or host name of a proxy used to traverse a firewall and relay user queries to network resources.
FirewallPort	Specifies the TCP port to be used for a proxy-based firewall.
FirewallUser	Identifies the user ID of the account authenticating to a proxy-based firewall.
FirewallPassword	Specifies the password of the user account authenticating to a proxy-based firewall.

Specifies the protocol the provider uses to tunnel traffic through a proxy-based firewall.

Remarks

A proxy-based firewall (or proxy firewall) is a network security device that acts as an intermediary between user requests and the resources they access. The proxy accepts the request of an authenticated user, tunnels through the firewall, and transmits the request to the appropriate server.

Because the proxy evaluates and transfers data backets on behalf of the requesting users, the users never connect directly with the servers, only with the proxy.

The following table provides port number information for each of the supported protocols.

Protocol	Default Port	Description
TUNNEL	80	The port where the Sync App opens a connection to Amazon Redshift. Traffic flows back and forth via the proxy at this location.
SOCKS4	1080	The port where the Sync App opens a connection to Amazon Redshift. SOCKS 4 then passes theFirewallUser value to the proxy, which determines whether the connection request should be granted.
SOCKS5	1080	The port where the Sync App sends data to Amazon Redshift. If the SOCKS 5 proxy requires authentication, set FirewallUser and FirewallPassword to credentials the proxy recognizes.

Identifies the IP address, DNS name, or host name of a proxy used to traverse a firewall and relay user queries to network resources.

Specifies whether the provider checks your system proxy settings for existing proxy server configurations, rather than using a manually specified proxy server.

Remarks

When this connection property is set to True, the Sync App checks your system proxy settings for existing proxy server configurations (no need to manually supply proxy server details).

This connection property takes precedence over other proxy settings. If you want to configure the Sync App to connect to a specific proxy server, set ProxyAutoDetect to False.

To connect to an HTTP proxy, see ProxyServer. For other proxies, such as SOCKS or tunneling, see FirewallType.

Identifies the hostname or IP address of the proxy server through which you want to route HTTP traffic.

Remarks

The Sync App only routes HTTP traffic through the proxy server specified in this connection property when ProxyAutoDetect is set to False.

If ProxyAutoDetect is set to True (the default), the Sync App instead routes HTTP traffic through the proxy server specified in your system proxy settings.

Identifies the TCP port on your specified proxy server that has been reserved for routing HTTP traffic to and from the client.

Remarks

The Sync App only routes HTTP traffic through the ProxyServer port specified in this connection property when ProxyAutoDetect is set to False.

If ProxyAutoDetect is set to True (the default), the Sync App instead routes HTTP traffic through the proxy server port specified in your system proxy settings.

For other proxy types, see FirewallType.

Specifies the authentication method the provider uses when authenticating to the proxy server specified in the ProxyServer connection property.

Remarks

Supported authentication types :

• BASIC: The Sync App performs HTTP basic authentication.
• DIGEST: The Sync App performs HTTP digest authentication.
• NTLM: The Sync App retrieves an NTLM token.
• NEGOTIATE: The Sync App retrieves an NTLM or Kerberos token based on the applicable protocol for authentication.
• NONE: Signifies that the ProxyServer does not require authentication.

For all values other than NONE, you must also set the ProxyUser and ProxyPassword connection properties.

If you need to use another authentication type, such as SOCKS 5 authentication, see FirewallType.

Provides the username of a user account registered with the proxy server specified in the ProxyServer connection property.

Remarks

The ProxyUser and ProxyPassword connection properties are used to connect and authenticate against the HTTP proxy specified in ProxyServer.

After selecting one of the available authentication types in ProxyAuthScheme, set this property as follows:

ProxyAuthScheme Value	Value to set for ProxyUser
BASIC	The username of a user registered with the proxy server.
DIGEST	The username of a user registered with the proxy server.
NEGOTIATE	The username of a Windows user who is a valid user in the domain or trusted domain that the proxy server is part of, in the format user@domain or domain\user.
NTLM	The username of a Windows user who is a valid user in the domain or trusted domain that the proxy server is part of, in the format user@domain or domain\user.
NONE	Do not set the ProxyPassword connection property.

Note: The Sync App only uses this username if ProxyAutoDetect is set to False. If ProxyAutoDetect is set to True (the default), the Sync App instead uses the username specified in your system proxy settings.

Specifies the password of the user specified in the ProxyUser connection property.

Remarks

The ProxyUser and ProxyPassword connection properties are used to connect and authenticate against the HTTP proxy specified in ProxyServer.

After selecting one of the available authentication types in ProxyAuthScheme, set this property as follows:

ProxyAuthScheme Value	Value to set for ProxyPassword
BASIC	The password associated with the proxy server user specified in ProxyUser.
DIGEST	The password associated with the proxy server user specified in ProxyUser.
NEGOTIATE	The password associated with the Windows user account specified in ProxyUser.
NTLM	The password associated with the Windows user account specified in ProxyUser.
NONE	Do not set the ProxyPassword connection property.

For SOCKS 5 authentication or tunneling, see FirewallType.

Note: The Sync App only uses this password if ProxyAutoDetect is set to False. If ProxyAutoDetect is set to True (the default), the Sync App instead uses the password specified in your system proxy settings.

Specifies the SSL type to use when connecting to the proxy server specified in the ProxyServer connection property.

Remarks

This property determines when to use SSL for the connection to the HTTP proxy specified by ProxyServer. You can set this connection property to the following values :

AUTO	Default setting. If ProxyServer is set to an HTTPS URL, the Sync App uses the TUNNEL option. If ProxyServer is set to an HTTP URL, the component uses the NEVER option.
ALWAYS	The connection is always SSL enabled.
NEVER	The connection is not SSL enabled.
TUNNEL	The connection is made through a tunneling proxy. The proxy server opens a connection to the remote host and traffic flows back and forth through the proxy.

Specifies a semicolon-separated list of destination hostnames or IPs that are exempt from connecting through the proxy server set in the ProxyServer connection property.

Remarks

The ProxyServer is used for all addresses, except for addresses defined in this property. Use semicolons to separate entries.

Note: The Sync App uses the system proxy settings by default, without further configuration needed. If you want to explicitly configure proxy exceptions for this connection, set ProxyAutoDetect to False.

This section provides a complete list of the Logging properties you can configure in the connection string for this provider.

---

Property	Description
LogModules	Specifies the core modules to include in the log file. Use a semicolon-separated list of module names. By default, all modules are logged.

Specifies the core modules to include in the log file. Use a semicolon-separated list of module names. By default, all modules are logged.

Remarks

The Sync App writes details about each operation it performs into the logfile specified by the Logfile connection property.

Each of these logged operations are assigned to a themed category called a module, and each module has a corresponding short code used to labels individual Sync App operations as belonging to that module.

When this connection property is set to a semicolon-separated list of module codes, only operations belonging to the specified modules are written to the logfile. Note that this only affects which operations are logged moving forward and doesn't retroactively alter the existing contents of the logfile. For example: INFO;EXEC;SSL;META;

By default, logged operations from all modules are included.

You can explicitly exclude a module by prefixing it with a "-". For example: -HTTP

To apply filters to submodules, identify them with the syntax <module name>.<submodule name>. For example, the following value causes the Sync App to only log actions belonging to the HTTP module, and further refines it to exclude actions belonging to the Res submodule of the HTTP module: HTTP;-HTTP.Res

Note that the logfile filtering triggered by the Verbosity connection property takes precedence over the filtering imposed by this connection property. This means that operations of a higher verbosity level than the level specified in the Verbosity connection property are not printed in the logfile, even if they belong to one of the modules specified in this connection property.

This section provides a complete list of the Schema properties you can configure in the connection string for this provider.

---

Property	Description
Location	Specifies the location of a directory containing schema files that define tables, views, and stored procedures. Depending on your service's requirements, this may be expressed as either an absolute path or a relative path.
BrowsableSchemas	Optional setting that restricts the schemas reported to a subset of all available schemas. For example, BrowsableSchemas=SchemaA,SchemaB,SchemaC .
Tables	Optional setting that restricts the tables reported to a subset of all available tables. For example, Tables=TableA,TableB,TableC .
Views	Optional setting that restricts the views reported to a subset of the available tables. For example, Views=ViewA,ViewB,ViewC .
IgnoredSchemas	Visibility restriction filter which is used to hide the list of schemas by metadata quering. For example, 'information_schema, pg_catalog'. Schema names are case sensitive.

Specifies the location of a directory containing schema files that define tables, views, and stored procedures. Depending on your service's requirements, this may be expressed as either an absolute path or a relative path.

Remarks

The Location property is only needed if you want to either customize definitions (for example, change a column name, ignore a column, etc.) or extend the data model with new tables, views, or stored procedures.

If left unspecified, the default location is %APPDATA%\\CData\\Redshift Data Provider\\Schema, where %APPDATA% is set to the user's configuration directory:

Platform	%APPDATA%
Windows	The value of the APPDATA environment variable
Linux	~/.config

Optional setting that restricts the schemas reported to a subset of all available schemas. For example, BrowsableSchemas=SchemaA,SchemaB,SchemaC .

Remarks

Listing all available database schemas can take extra time, thus degrading performance. Providing a list of schemas in the connection string saves time and improves performance.

Optional setting that restricts the tables reported to a subset of all available tables. For example, Tables=TableA,TableB,TableC .

Remarks

Listing all available tables from some databases can take extra time, thus degrading performance. Providing a list of tables in the connection string saves time and improves performance.

If there are lots of tables available and you already know which ones you want to work with, you can use this property to restrict your viewing to only those tables. To do this, specify the tables you want in a comma-separated list. Each table should be a valid SQL identifier with any special characters escaped using square brackets, double-quotes or backticks. For example, Tables=TableA,[TableB/WithSlash],WithCatalog.WithSchema.`TableC With Space`.

Note: If you are connecting to a data source with multiple schemas or catalogs, you must specify each table you want to view by its fully qualified name. This avoids ambiguity between tables that may exist in multiple catalogs or schemas.

Optional setting that restricts the views reported to a subset of the available tables. For example, Views=ViewA,ViewB,ViewC .

Remarks

Listing all available views from some databases can take extra time, thus degrading performance. Providing a list of views in the connection string saves time and improves performance.

If there are lots of views available and you already know which ones you want to work with, you can use this property to restrict your viewing to only those views. To do this, specify the views you want in a comma-separated list. Each view should be a valid SQL identifier with any special characters escaped using square brackets, double-quotes or backticks. For example, Views=ViewA,[ViewB/WithSlash],WithCatalog.WithSchema.`ViewC With Space`.

Note: If you are connecting to a data source with multiple schemas or catalogs, you must specify each view you want to examine by its fully qualified name. This avoids ambiguity between views that may exist in multiple catalogs or schemas.

Visibility restriction filter which is used to hide the list of schemas by metadata quering. For example, 'information_schema, pg_catalog'. Schema names are case sensitive.

Remarks

By default, restrictions are not applied. The property is inactive when BrowsableSchemas is specified.

This section provides a complete list of the Miscellaneous properties you can configure in the connection string for this provider.

---

Property	Description
AllowPreparedStatement	Prepare a query statement before its execution.
FetchResultSetMetadata	This field sets whether the provider retrieves metadata pertaining to the schema and table name for resultset columns returned by the server.
IncludeTableTypes	If set to true, the provider will query for the types of individual tables and views.
InsertMode	Specifies what method to use when inserting bulk data. By default DML mode is used.
IsServerless	The provider cannot detect endpoint to connect, if you are using a custom domain names for connections. Set this property to True when you are connecting to the Amazon Redshift serverless instance, as well specify the property AWSRegion in this case.
LZ4Compression	When set the driver notifies the server to compress data packets with lz4 compression algorithm.
MaxRows	Specifies the maximum number of rows returned for queries that do not include either aggregation or GROUP BY.
Other	Specifies advanced connection properties for specialized scenarios. Use this property only under the guidance of our Support team to address specific issues.
QueryPassthrough	This option passes the query to the Amazon Redshift server as is.
RedshiftToS3RoleARN	The Amazon Resource Name of the role to use when authenticating S3 with IAM role by the COPY command for the bulk inserts.
S3Bucket	Specifies the name of AWS S3 bucket to upload bulk data for staging.
S3BucketFolder	Specifies the name of the folder in AWS S3 bucket to upload bulk data for staging. By default bulk data are staged in the root folder.
StripOutNulls	When set the null characters are stripped out from character values in bulk operations.
Timeout	Specifies the maximum time, in seconds, that the provider waits for a server response before throwing a timeout error.
TimeZone	Set time zone for the current session.
UseUIDForStaging	Use this property in combination with InsertMode assigned with S3Staging or S3StagingWithIAM. By default the the driver creates staging files with names that prepend the targeted table's name, so the files are overwritten between sessions. When the property is set to True , the provider additionally attaches temporary unique identifiers to these names. It may be required if you use parallel jobs to insert rows into the same table. Thus, the staging files are not overwritten by the jobs. A caveat is that using this property adds to the number of staging files put onto S3 bucket, since the file names are not controlled by the driver between different sessions. In this case you may want to define an AWS S3 policy on the bucket to remove staging files that were stored in a bucket automatically.

Prepare a query statement before its execution.

Remarks

If the AllowPreparedStatement property is set to false, statements are parsed each time they are executed. Setting this property to false can be useful if you are executing many different queries only once.

If you are executing the same query repeatedly, you will generally see better performance by leaving this property at the default, true. Preparing the query avoids recompiling the same query over and over. However, prepared statements also require the Sync App to keep the connection active and open while the statement is prepared.

This field sets whether the provider retrieves metadata pertaining to the schema and table name for resultset columns returned by the server.

Remarks

By default, the Sync App will not request that the server provides detailed information about resultset columns like the table name or schema name. It requires issuing additional metadata queries via Sync App , and it may affect query performance essentially in some scenarios. Consider setting this property to True when you need such detailed descriptive information for the resultset columns.

If set to true, the provider will query for the types of individual tables and views.

Remarks

If set to true, the Sync App will query Redshift for the types of individual tables and views.

Specifies what method to use when inserting bulk data. By default DML mode is used.

Remarks

When this is set to DML the Sync App uses Insert SQL statements to upload bulk data.

When this is set to S3Staging the Sync App uses the bulk upload API to upload data to the AWS S3 staging folder.

Bulk Insertion

InsertMode provides the following options for executing a bulk insert operation by the driver:

1. DML: This is the default option for sending multiple INSERT statements to the server by the driver in bulk. In this case, the driver issues a multi-row INSERT statement with respective syntax supported by the server. See Use a multi-row insert in the Amazon Redshift documentation.
2. S3Staging: This option involves two steps. Initially, multiple rows are streamed to the Amazon S3 bucket in CSV format. A staging CSV file is then created in the bucket. In the second step, Redshift's COPY FROM command copies the staged CSV file to a database. See COPY in the Amazon Redshift documentation for more information.

   The minimum set of policies required to connect AWS S3 by an IAM user, or a role assumed by it, are:

   • S3:ListBucket
   • S3:GetObject
   • S3:PutObject.

   Note that this mode uses your AWSAccessKey and AWSSecretKey in COPY commands that are sent to the server. This could present a security concern. If you want to hide sensitive information, use the S3StagingWithIAM mode instead.

3. S3StagingWithIAM: This option is similar to S3Staging, but it uses an IAM role parameter for the COPY command.

   The AWSAccessKey and AWSSecretKey are still required to connect in this mode, but they are not be included in the COPY commands sent to Redshift.

NOTE:If you choose the S3Staging or S3StagingWithIAM insert mode, and if you set the UseUIDForStaging connection property to True, you may want to define an AWS S3 policy on the bucket to remove staging files that are automatically stored in the bucket.

See also:

• AllowPreparedStatement
• RedshiftToS3RoleARN

The provider cannot detect endpoint to connect, if you are using a custom domain names for connections. Set this property to True when you are connecting to the Amazon Redshift serverless instance, as well specify the property AWSRegion in this case.

Remarks

If set to True, the Sync App will connect to serverless instance of the Amazon Redshift. By default, the property is set to False, and the Sync App will try to detect endpoint to connect.

When set the driver notifies the server to compress data packets with lz4 compression algorithm.

Remarks

Specifies the maximum number of rows returned for queries that do not include either aggregation or GROUP BY.

Remarks

The default value for this property, -1, means that no row limit is enforced unless the query explicitly includes a LIMIT clause. (When a query includes a LIMIT clause, the value specified in the query takes precedence over the MaxRows setting.)

Setting MaxRows to a whole number greater than 0 ensures that queries do not return excessively large result sets by default.

This property is useful for optimizing performance and preventing excessive resource consumption when executing queries that could otherwise return very large datasets.

Specifies advanced connection properties for specialized scenarios. Use this property only under the guidance of our Support team to address specific issues.

Remarks

This property allows advanced users to configure hidden properties for specialized situations, with the advice of our Support team. These settings are not required for normal use cases but can address unique requirements or provide additional functionality. To define multiple properties, use a semicolon-separated list.

Note: It is strongly recommended to set these properties only when advised by the Support team to address specific scenarios or issues.

Integration and Formatting

Property	Description
DefaultColumnSize	Sets the default length of string fields when the data source does not provide column length in the metadata. The default value is 2000.
ConvertDateTimeToGMT=True	Converts date-time values to GMT, instead of the local time of the machine. The default value is False (use local time).
RecordToFile=filename	Records the underlying socket data transfer to the specified file.

This option passes the query to the Amazon Redshift server as is.

Remarks

When this is set, queries are passed through directly to Amazon Redshift.

The Amazon Resource Name of the role to use when authenticating S3 with IAM role by the COPY command for the bulk inserts.

Remarks

By default, if this property is not set, the COPY command uses 'default' value for the IAM role.

Specifies the name of AWS S3 bucket to upload bulk data for staging.

Remarks

Specifies the name of the folder in AWS S3 bucket to upload bulk data for staging. By default bulk data are staged in the root folder.

Remarks

When set the null characters are stripped out from character values in bulk operations.

Remarks

Specifies the maximum time, in seconds, that the provider waits for a server response before throwing a timeout error.

Remarks

The timeout applies to each individual communication with the server rather than the entire query or operation. For example, a query could continue running beyond 60 seconds if each paging call completes within the timeout limit.

Timeout is set to 60 seconds by default. To disable timeouts, set this property to 0.

Disabling the timeout allows operations to run indefinitely until they succeed or fail due to other conditions such as server-side timeouts, network interruptions, or resource limits on the server.

Note: Use this property cautiously to avoid long-running operations that could degrade performance or result in unresponsive behavior.

Set time zone for the current session.

Remarks

If the TimeZone property is not set, provider uses client system time zone. Setting this property can be useful when you need the server to convert time with time zone and timestamp with timezone values to specific time zone, which is different than client's system time zone.

Use this property in combination with InsertMode assigned with S3Staging or S3StagingWithIAM. By default the the driver creates staging files with names that prepend the targeted table's name, so the files are overwritten between sessions. When the property is set to True , the provider additionally attaches temporary unique identifiers to these names. It may be required if you use parallel jobs to insert rows into the same table. Thus, the staging files are not overwritten by the jobs. A caveat is that using this property adds to the number of staging files put onto S3 bucket, since the file names are not controlled by the driver between different sessions. In this case you may want to define an AWS S3 policy on the bucket to remove staging files that were stored in a bucket automatically.

2. GRANT OF RIGHTS

a) Subject to the terms of this Agreement, each Contributor hereby grants Recipient a non-exclusive, worldwide, royalty-free copyright license to reproduce, prepare derivative works of, publicly display, publicly perform, distribute and sublicense the Contribution of such Contributor, if any, and such derivative works, in source code and object code form.

b) Subject to the terms of this Agreement, each Contributor hereby grants Recipient a non-exclusive, worldwide, royalty-free patent license under Licensed Patents to make, use, sell, offer to sell, import and otherwise transfer the Contribution of such Contributor, if any, in source code and object code form. This patent license shall apply to the combination of the Contribution and the Program if, at the time the Contribution is added by the Contributor, such addition of the Contribution causes such combination to be covered by the Licensed Patents. The patent license shall not apply to any other combinations which include the Contribution. No hardware per se is licensed hereunder.

c) Recipient understands that although each Contributor grants the licenses to its Contributions set forth herein, no assurances are provided by any Contributor that the Program does not infringe the patent or other intellectual property rights of any other entity. Each Contributor disclaims any liability to Recipient for claims brought by any other entity based on infringement of intellectual property rights or otherwise. As a condition to exercising the rights and licenses granted hereunder, each Recipient hereby assumes sole responsibility to secure any other intellectual property rights needed, if any. For example, if a third party patent license is required to allow Recipient to distribute the Program, it is Recipient's responsibility to acquire that license before distributing the Program.

d) Each Contributor represents that to its knowledge it has sufficient copyright rights in its Contribution, if any, to grant the copyright license set forth in this Agreement.

3. REQUIREMENTS

A Contributor may choose to distribute the Program in object code form under its own license agreement, provided that:

a) it complies with the terms and conditions of this Agreement; and

Contributors may not remove or alter any copyright notices contained within the Program.

Each Contributor must identify itself as the originator of its Contribution, if any, in a manner that reasonably allows subsequent Recipients to identify the originator of the Contribution.

4. COMMERCIAL DISTRIBUTION

Commercial distributors of software may accept certain responsibilities with respect to end users, business partners and the like. While this license is intended to facilitate the commercial use of the Program, the Contributor who includes the Program in a commercial product offering should do so in a manner which does not create potential liability for other Contributors. Therefore, if a Contributor includes the Program in a commercial product offering, such Contributor ("Commercial Contributor") hereby agrees to defend and indemnify every other Contributor ("Indemnified Contributor") against any losses, damages and costs (collectively "Losses") arising from claims, lawsuits and other legal actions brought by a third party against the Indemnified Contributor to the extent caused by the acts or omissions of such Commercial Contributor in connection with its distribution of the Program in a commercial product offering. The obligations in this section do not apply to any claims or Losses relating to any actual or alleged intellectual property infringement. In order to qualify, an Indemnified Contributor must: a) promptly notify the Commercial Contributor in writing of such claim, and b) allow the Commercial Contributor to control, and cooperate with the Commercial Contributor in, the defense and any related settlement negotiations. The Indemnified Contributor may participate in any such claim at its own expense.

For example, a Contributor might include the Program in a commercial product offering, Product X. That Contributor is then a Commercial Contributor. If that Commercial Contributor then makes performance claims, or offers warranties related to Product X, those performance claims and warranties are such Commercial Contributor's responsibility alone. Under this section, the Commercial Contributor would have to defend claims against the other Contributors related to those performance claims and warranties, and if a court requires any other Contributor to pay any damages as a result, the Commercial Contributor must pay those damages.

5. NO WARRANTY

EXCEPT AS EXPRESSLY SET FORTH IN THIS AGREEMENT, THE PROGRAM IS PROVIDED ON AN "AS IS" BASIS, WITHOUT WARRANTIES OR CONDITIONS OF ANY KIND, EITHER EXPRESS OR IMPLIED INCLUDING, WITHOUT LIMITATION, ANY WARRANTIES OR CONDITIONS OF TITLE, NON-INFRINGEMENT, MERCHANTABILITY OR FITNESS FOR A PARTICULAR PURPOSE. Each Recipient is solely responsible for determining the appropriateness of using and distributing the Program and assumes all risks associated with its exercise of rights under this Agreement, including but not limited to the risks and costs of program errors, compliance with applicable laws, damage to or loss of data, programs or equipment, and unavailability or interruption of operations.

6. DISCLAIMER OF LIABILITY

EXCEPT AS EXPRESSLY SET FORTH IN THIS AGREEMENT, NEITHER RECIPIENT NOR ANY CONTRIBUTORS SHALL HAVE ANY LIABILITY FOR ANY DIRECT, INDIRECT, INCIDENTAL, SPECIAL, EXEMPLARY, OR CONSEQUENTIAL DAMAGES (INCLUDING WITHOUT LIMITATION LOST PROFITS), HOWEVER CAUSED AND ON ANY THEORY OF LIABILITY, WHETHER IN CONTRACT, STRICT LIABILITY, OR TORT (INCLUDING NEGLIGENCE OR OTHERWISE) ARISING IN ANY WAY OUT OF THE USE OR DISTRIBUTION OF THE PROGRAM OR THE EXERCISE OF ANY RIGHTS GRANTED HEREUNDER, EVEN IF ADVISED OF THE POSSIBILITY OF SUCH DAMAGES.

7. GENERAL

If any provision of this Agreement is invalid or unenforceable under applicable law, it shall not affect the validity or enforceability of the remainder of the terms of this Agreement, and without further action by the parties hereto, such provision shall be reformed to the minimum extent necessary to make such provision valid and enforceable.

If Recipient institutes patent litigation against a Contributor with respect to a patent applicable to software (including a cross-claim or counterclaim in a lawsuit), then any patent licenses granted by that Contributor to such Recipient under this Agreement shall terminate as of the date such litigation is filed. In addition, if Recipient institutes patent litigation against any entity (including a cross-claim or counterclaim in a lawsuit) alleging that the Program itself (excluding combinations of the Program with other software or hardware) infringes such Recipient's patent(s), then such Recipient's rights granted under Section 2(b) shall terminate as of the date such litigation is filed.

All Recipient's rights under this Agreement shall terminate if it fails to comply with any of the material terms or conditions of this Agreement and does not cure such failure in a reasonable period of time after becoming aware of such noncompliance. If all Recipient's rights under this Agreement terminate, Recipient agrees to cease use and distribution of the Program as soon as reasonably practicable. However, Recipient's obligations under this Agreement and any licenses granted by Recipient relating to the Program shall continue and survive.

Everyone is permitted to copy and distribute copies of this Agreement, but in order to avoid inconsistency the Agreement is copyrighted and may only be modified in the following manner.

No one other than the Agreement Steward has the right to modify this Agreement. IBM is the initial Agreement Steward. IBM may assign the responsibility to serve as the Agreement Steward to a suitable separate entity. Each new version of the Agreement will be given a distinguishing version number. The Program (including Contributions) may always be distributed subject to the version of the Agreement under which it was received. In addition, after a new version of the Agreement is published, Contributor may elect to distribute the Program (including its Contributions) under the new version. Except as expressly stated in Sections 2(a) and 2(b) above, Recipient receives no rights or licenses to the intellectual property of any Contributor under this Agreement, whether expressly, by implication, estoppel or otherwise. All rights in the Program not expressly granted under this Agreement are reserved.
