Create a connection to Amazon Redshift by navigating to the Connections page in the Sync App application and selecting the corresponding icon in the Add Connections panel. 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.

Required properties are listed under the Settings tab. The Advanced tab lists connection properties that are not typically required.

Connecting to Amazon Redshift

The following connection properties are usually required in order 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.

You can also optionally set the following:

• Port: The port of the server hosting the Amazon Redshift database. 5439 by default.

You can 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 will be 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. For that configure the following connection properties:

• SSLClientCert: Set this to the name of the certificate store for the client certificate. 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. 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.

The following is the example connection string to connect Amazon Redshift using standard user/password and inactive SSL encryption:

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

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; see the SSLServerCert property under "Connection String Options" for more information.

Firewall and Proxy

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

Logging

See Logging for an overview of configuration settings that can be used to refine CData logging. For basic logging, you only need to set two connection properties, but there are numerous features that support more refined logging, where you can select subsets of information to be logged using the LogModules connection property.

Customizing the SSL Configuration

By default, the Sync App attempts to negotiate SSL/TLS by checking the server's certificate against the system's trusted certificate store.

To specify another certificate, see the SSLServerCert property for the available formats to do so.

Client SSL Certificates

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

Property	Description
AzureTenant	The Microsoft Online tenant being used to access data. If not specified, your default tentant will be used.

The Microsoft Online tenant being used to access data. If not specified, your default tentant will be used.

Remarks

The Microsoft Online tenant being used to access data. For instance, contoso.onmicrosoft.com. Alternatively, specify the tenant Id. This value is the directory Id in the Azure Portal > Azure Active Directory > Properties.

Typically it is not necessary to specify the Tenant. This can be automatically determined by Microsoft when using the OAuthGrantType set to CODE (default). However, it may fail in the case that the user belongs to multiple tenants. For instance, if an Admin of domain A invites a user of domain B to be a guest user. The user will now belong to both tenants. It is a good practice to specify the Tenant, although in general things should normally work without having to specify it.

The AzureTenant is required when setting OAuthGrantType to CLIENT. When using client credentials, there is no user context. The credentials are taken from the context of the app itself. While Microsoft still allows client credentials to be obtained without specifying which Tenant, it has a much lower probability of picking the specific tenant you want to work with. For this reason, we require AzureTenant to be explicitly stated for all client credentials connections to ensure you get credentials that are applicable for the domain you intend to connect to.

The SSLClientCertType field specifies the type of the certificate store specified by SSLClientCert. If the store is password protected, specify the password in SSLClientCertPassword.

SSLClientCert is used in conjunction with the SSLClientCertSubject field in order to specify client certificates. If SSLClientCert has a value, and SSLClientCertSubject is set, a search for a certificate is initiated. See SSLClientCertSubject for more information.

Designations of certificate stores are platform-dependent.

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.

In Java, the certificate store normally is a file containing certificates and optional private keys.

When the certificate store type is PFXFile, this property must be set to the name of the file. When the type is PFXBlob, the property must be set to the binary contents of a PFX file (for example, PKCS12 certificate store).

The type of key store containing the TLS/SSL client certificate.

Remarks

This property can take one of the following values:

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.

PPKFILE	The certificate store is the name of a file that contains a PuTTY Private Key (PPK).
XMLFILE	The certificate store is the name of a file that contains a certificate in XML format.
XMLBLOB	The certificate store is a string that contains a certificate in XML format.

The password for the TLS/SSL client certificate.

Remarks

If the certificate store is of a type that requires a password, this property is used to specify that password to open the certificate store.

The subject of the TLS/SSL 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 example, "CN=www.server.com, OU=test, C=US, [email protected]". The common fields and their meanings are shown below.

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

If a field value contains a comma, it must be quoted.

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

Remarks

If using a TLS/SSL connection, this property can be used to specify the TLS/SSL certificate to be accepted from the server. Any other certificate that is not trusted by the machine is 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 authentication method to be used to log on to an SFTP server.

Remarks

• None: No authentication will be performed. The current User value is ignored, and the connection will be logged in as anonymous.
• Password: The Sync App will use the values of User and Password to authenticate the user.
• Public_Key: The Sync App will use the values of User and SSHClientCert to authenticate the user. SSHClientCert must have a private key available for this authentication method to succeed.

A private key to be used for authenticating the user.

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 only used when authenticating to SFTP servers with SSHAuthMode set to PublicKey and SSHClientCert set to a private key.

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.

ProxyExceptions	A semicolon separated list of destination hostnames or IPs that are exempt from connecting through the ProxyServer .

This indicates whether to use the system proxy settings or not. This takes precedence over other proxy settings, so you'll need to set ProxyAutoDetect to FALSE in order use custom proxy settings.

Remarks

This takes precedence over other proxy settings, so you'll need to set ProxyAutoDetect to FALSE in order use custom proxy settings.

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

The hostname or IP address of a proxy to route HTTP traffic through.

Remarks

The hostname or IP address of a proxy to route HTTP traffic through. The Sync App can use the HTTP, Windows (NTLM), or Kerberos authentication types to authenticate to an HTTP proxy.

If you need to connect through a SOCKS proxy or tunnel the connection, see FirewallType.

By default, the Sync App uses the system proxy. If you need to use another proxy, set ProxyAutoDetect to false.

The TCP port the ProxyServer proxy is running on.

Remarks

The port the HTTP proxy is running on that you want to redirect HTTP traffic through. Specify the HTTP proxy in ProxyServer. For other proxy types, see FirewallType.

The authentication type to use to authenticate to the ProxyServer proxy.

Remarks

This value specifies the authentication type to use to authenticate to the HTTP proxy specified by ProxyServer and ProxyPort.

Note that the Sync App will use the system proxy settings by default, without further configuration needed; if you want to connect to another proxy, you will need to set ProxyAutoDetect to false, in addition to ProxyServer and ProxyPort. To authenticate, set ProxyAuthScheme and set ProxyUser and ProxyPassword, if needed.

The authentication type can be one of the following:

• BASIC: The Sync App performs HTTP BASIC authentication.
• DIGEST: The Sync App performs HTTP DIGEST authentication.
• NEGOTIATE: The Sync App retrieves an NTLM or Kerberos token based on the applicable protocol for authentication.
• PROPRIETARY: The Sync App does not generate an NTLM or Kerberos token. You must supply this token in the Authorization header of the HTTP request.

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

A user name to be used to authenticate to the ProxyServer proxy.

Remarks

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

You can select one of the available authentication types in ProxyAuthScheme. If you are using HTTP authentication, set this to the user name of a user recognized by the HTTP proxy. If you are using Windows or Kerberos authentication, set this property to a user name in one of the following formats:

user@domain
domain\user

A password to be used to authenticate to the ProxyServer proxy.

Remarks

This property is used to authenticate to an HTTP proxy server that supports NTLM (Windows), Kerberos, or HTTP authentication. To specify the HTTP proxy, you can set ProxyServer and ProxyPort. To specify the authentication type, set ProxyAuthScheme.

If you are using HTTP authentication, additionally set ProxyUser and ProxyPassword to HTTP proxy.

If you are using NTLM authentication, set ProxyUser and ProxyPassword to your Windows password. You may also need these to complete Kerberos authentication.

For SOCKS 5 authentication or tunneling, see FirewallType.

By default, the Sync App uses the system proxy. If you want to connect to another proxy, set ProxyAutoDetect to false.

The SSL type to use when connecting to the ProxyServer proxy.

Remarks

This property determines when to use SSL for the connection to an HTTP proxy specified by ProxyServer. This value can be AUTO, ALWAYS, NEVER, or TUNNEL. The applicable values are the following:

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

A semicolon separated list of destination hostnames or IPs that are exempt from connecting through the ProxyServer .

Remarks

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

Note that 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, you need to set ProxyAutoDetect = false, and configure ProxyServer and ProxyPort. To authenticate, set ProxyAuthScheme and set ProxyUser and ProxyPassword, if needed.

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

---

Property	Description
LogModules	Core modules to be included in the log file.

Core modules to be included in the log file.

Remarks

Only the modules specified (separated by ';') will be included in the log file. By default all modules are included.

See the Logging page for an overview.

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

---

Property	Description
Location	A path to the directory that contains the schema files defining tables, views, and stored procedures.
BrowsableSchemas	This property restricts the schemas reported to a subset of the available schemas. For example, BrowsableSchemas=SchemaA,SchemaB,SchemaC.
Tables	This property restricts the tables reported to a subset of the available tables. For example, Tables=TableA,TableB,TableC.
Views	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.

A path to the directory that contains the schema files defining tables, views, and stored procedures.

Remarks

The path to a directory which contains the schema files for the Sync App (.rsd files for tables and views, .rsb files for stored procedures). The folder location can be a relative path from the location of the executable. The Location property is only needed if you want to customize definitions (for example, change a column name, ignore a column, and so on) 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" with %APPDATA% being set to the user's configuration directory:

This property restricts the schemas reported to a subset of the available schemas. For example, BrowsableSchemas=SchemaA,SchemaB,SchemaC.

Remarks

Listing the schemas from databases can be expensive. Providing a list of schemas in the connection string improves the performance.

This property restricts the tables reported to a subset of the available tables. For example, Tables=TableA,TableB,TableC.

Remarks

Listing the tables from some databases can be expensive. Providing a list of tables in the connection string improves the performance of the Sync App.

This property can also be used as an alternative to automatically listing views if you already know which ones you want to work with and there would otherwise be too many to work with.

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 that when connecting to a data source with multiple schemas or catalogs, you will need to provide the fully qualified name of the table in this property, as in the last example here, to avoid ambiguity between tables that exist in multiple catalogs or schemas.

Restricts the views reported to a subset of the available tables. For example, Views=ViewA,ViewB,ViewC.

Remarks

Listing the views from some databases can be expensive. Providing a list of views in the connection string improves the performance of the Sync App.

This property can also be used as an alternative to automatically listing views if you already know which ones you want to work with and there would otherwise be too many to work with.

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 that when connecting to a data source with multiple schemas or catalogs, you will need to provide the fully qualified name of the table in this property, as in the last example here, to avoid ambiguity between tables that 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.

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 is getting detailed information about resultset columns from 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.
MaxRows	Limits the number of rows returned rows when no aggregation or group by is used in the query. This helps avoid performance issues at design time.
Other	These hidden properties are used only in specific use cases.
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. See InsertMode .
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	The value in seconds until the timeout error is thrown, canceling the operation.
TimeZone	Set time zone for the current session.

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 is getting detailed information about resultset columns from the server.

Remarks

By default, the Sync App will not request server to provide too detailed information about resultset columns (like the table name, for example) when the query is succeeding, because it requires issuing additional metaquery by the Sync App, and may affect query performance essentially in some scenarios. Consider this property when you are requiring all details about resultset columns together with the query result.

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 two options for executing a bulk insert operation by the driver.

1. InsertMode=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. For more information, see Use a multi-row insert - Amazon Redshift
2. InsertMode=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 command COPY FROM copies the staged CSV file to a database. See, for example: https://docs.aws.amazon.com/redshift/latest/dg/r_COPY.html. 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 and S3:PutObject.
3. InsertMode=S3StagingWithIAM This option is similar to S3Staging, but it uses IAM role parameter for the COPY command. See AllowPreparedStatement property.

To decide which insert mode you should use, compare the performance of these two options. How well each option performs depends on your environment, so you can use this comparison to make your decision.

Limits the number of rows returned rows when no aggregation or group by is used in the query. This helps avoid performance issues at design time.

Remarks

Limits the number of rows returned rows when no aggregation or group by is used in the query. This helps avoid performance issues at design time.

These hidden properties are used only in specific use cases.

Remarks

The properties listed below are available for specific use cases. Normal driver use cases and functionality should not require these properties.

Specify multiple properties in a semicolon-separated list.

Integration and Formatting

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	Determines whether to convert date-time values to GMT, instead of the local time of the machine.
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. See InsertMode .

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

The value in seconds until the timeout error is thrown, canceling the operation.

Remarks

If Timeout = 0, operations do not time out. The operations run until they complete successfully or until they encounter an error condition.

If Timeout expires and the operation is not yet complete, the Sync App throws an exception.

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.
