The CData Sync App provides a straightforward way to continuously pipeline your Apache HBase data to any database, data lake, or data warehouse, making it easily available for Analytics, Reporting, AI, and Machine Learning.
The Apache HBase connector can be used from the CData Sync application to pull data from Apache HBase and move it to any of the supported destinations.
The Sync App models HBase data as a read/write, relational database. The Sync App can connect to HBase REST Server 0.0.3, available in HBase version 0.98 and above.
In most distributions, you can enter the following command to start the HBase REST server in the foreground:
hbase rest start -p <port>
For further information about the HBase REST server, consult your Hadoop distribution's documentation.
For required properties, see the Settings tab.
For connection properties that are not typically required, see the Advanced tab.
To connect to Apache HBase, set these parameters:
The CData Sync App supports the following authentication schemes:
By default, no authentication (alternatively known as "anonymous" authentication) is used. Set AuthScheme to None to explicitly enforce no authentication.
To use Basic authentication, set the following:
To authenticate to Apache HBase with Kerberos, set AuthScheme to NEGOTIATE.
Authenticating to Apache HBase via Kerberos requires you to define authentication properties and to choose how Kerberos should retrieve authentication tickets.
The Sync App provides three ways to retrieve the required Kerberos ticket, depending on whether or not the KRB5CCNAME and/or KerberosKeytabFile variables exist in your environment.
MIT Kerberos Credential Cache File
This option enables you to use the MIT Kerberos Ticket Manager or kinit command to get tickets. With this option there is no need to set the User or Password connection properties.
This option requires that KRB5CCNAME has been created in your system.
To enable ticket retrieval via MIT Kerberos Credential Cache Files:
If the ticket is successfully obtained, the ticket information appears in Kerberos Ticket Manager and is stored in the credential cache file.
The Sync App uses the cache file to obtain the Kerberos ticket to connect to Apache HBase.
Note: If you would prefer not to edit KRB5CCNAME, you can use the KerberosTicketCache property to set the file path manually. After this is set, the Sync App uses the specified cache file to obtain the Kerberos ticket to connect to Apache HBase.
Keytab File
If your environment lacks the KRB5CCNAME environment variable, you can retrieve a Kerberos ticket using a Keytab File.
To use this method, set the User property to the desired username, and set the KerberosKeytabFile property to a file path pointing to the keytab file associated with the user.
User and Password
If your environment lacks the KRB5CCNAME environment variable and the KerberosKeytabFile property has not been set, you can retrieve a ticket using a user and password combination.
To use this method, set the User and Password properties to the user/password combination that you use to authenticate with Apache HBase.
To enable this kind of cross-realm authentication, set the KerberosRealm and KerberosKDC properties to the values required for user authentication. Also, set the KerberosServiceRealm and KerberosServiceKDC properties to the values required to obtain the service ticket.
You can use the following properties to configure automatic data type detection, which is enabled by default.
This section details a selection of advanced features of the Apache HBase Sync App.
The Sync App supports the use of user defined views, virtual tables whose contents are decided by a pre-configured user defined query. These views are useful when you cannot directly control queries being issued to the drivers. For an overview of creating and configuring custom views, see User Defined Views .
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" .
Configure the Sync App for compliance with Firewall and Proxy, including Windows proxies and HTTP proxies. You can also set up tunnel connections.
For further information, see Query Processing.
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.
To authenticate to an HTTP proxy, set the following:
Set the following properties:
The CData Sync App models the Apache HBase REST APIs as relational tables and stored procedures that can be accessed with standard SQL. This enables access from standards-based tools.
The table definitions are dynamically retrieved. When you connect, the Sync App connects to Apache HBase and gets the list of tables and the metadata for the tables by querying the HBase REST server. Any changes to the remote data are immediately reflected in your queries.
Stored Procedures are function-like interfaces to the data source. Stored procedures model actions that typically cannot be represented as SELECT, INSERT, UPDATE, or DELETE statements. The stored procedures of the Sync App surface the capabilities of the DDL (data definition language) in Apache HBase.
Stored procedures are function-like interfaces that extend the functionality of the Sync App beyond simple SELECT/INSERT/UPDATE/DELETE operations with Apache HBase.
Stored procedures accept a list of parameters, perform their intended function, and then return any relevant response data from Apache HBase, along with an indication of whether the procedure succeeded or failed.

This section provides a complete list of the Kerberos properties you can configure in the connection string for this provider.
| Property | Description |
| KerberosKDC | Identifies the Kerberos Key Distribution Center (KDC) service used to authenticate the user. (SPNEGO or Windows authentication only). |
| KerberosRealm | Identifies the Kerberos Realm used to authenticate the user. |
| KerberosSPN | Identifies the service principal name (SPN) for the Kerberos Domain Controller. |

| KerberosServiceKDC | Identifies the service's Kerberos Key Distribution Center (KDC). |
| KerberosTicketCache | Specifies the full file path to an MIT Kerberos credential cache file. |
Identifies the Kerberos Key Distribution Center (KDC) service used to authenticate the user. (SPNEGO or Windows authentication only).
The Kerberos properties are used when using SPNEGO or Windows Authentication. The Sync App requests session tickets and temporary session keys from the Kerberos KDC service, which is usually co-located with the domain controller.
If KerberosKDC is not specified, the Sync App tries to detect these properties automatically from the following locations:
Identifies the Kerberos Realm used to authenticate the user.
A realm is a logical network, similar to a domain, that defines a group of systems under the same master KDC. Some realms are hierarchical, where one realm is a superset of the other realm, but usually realms are nonhierarchical (or “direct”) and the mapping between the two realms must be defined. Kerberos cross-realm authentication enables authentication across realms. Each realm only needs to have a principal entry for the other realm in its KDC.
The Kerberos properties are used when using SPNEGO or Windows Authentication. The Sync App requests session tickets and temporary session keys from the Kerberos KDC service, which is usually co-located with the domain controller. The Kerberos Realm can be configured by an administrator to be any string, but it is usually based on the domain name.
If Kerberos Realm is not specified, the Sync App will attempt to detect these properties automatically from the following locations:
Identifies the service principal name (SPN) for the Kerberos Domain Controller.
If the SPN on the Kerberos Domain Controller is not the same as the URL that you are authenticating to, use this property to set the SPN to the KDC's URL.
Confirms the principal name for the Kerberos Domain Controller, which uses the format host/user@realm.
If there is a Kerberos principal, that Kerberos principal name should always be used to authenticate to the database.
Identifies the Keytab file containing your pairs of Kerberos principals and encrypted keys.
A keytab (short for “key table”) stores long-term keys for one or more principals. In most cases, end users authenticate to the KDC using their client secret (password). However, in situations where authentication or re-authentication happen using automated scripts and applications, it may be more efficient to use a keytab, which sends passwords to the KDC in encrypted form, automatically.
Keytabs are normally represented by files in a standard format, and named using the format type:value. Usually type is FILE and value is the absolute pathname of the file. The other possible value for type is MEMORY, which indicates a temporary keytab stored in the memory of the current process.
A keytab contains one or more entries, where each entry consists of a timestamp (indicating when the entry was written to the keytab), a principal name, a key version number, an encryption type, and the encryption key itself. They can be generated using kutil.
For example:
[admin@myhost]# ktutil ktutil: addent -password -p starlord/[email protected] -k 1 -e aes256-cts-hmac-sha1-96 Password for starlord/myhost.galaxy.com: ktutil: addent -password -p starlord/[email protected] -k 1 -e aes128-cts-hmac-sha1-96 Password for starlord/myhost.galaxy.com: ktutil: addent -password -p starlord/[email protected] -k 1 -e des3-cbc-sha1 Password for starlord/myhost.galaxy.com: ktutil: wkt /path/to/starlord.keytab
Note: You must create principals for all authentication methods (encryption types) you want to support.
To display a keytab, use klist -k.
Identifies the service's Kerberos realm. (Cross-realm authentication only).
The KerberosServiceRealm is used to specify a service's KerberosRealm when using cross-realm Kerberos authentication.
In most cases, a single realm and KDC machine are used to perform the Kerberos authentication, which means that this property would not be required. However, the property is available for complex setups where a different realm and KDC machine are used to obtain an authentication ticket (AS request) and a service ticket (TGS request).
Identifies the service's Kerberos Key Distribution Center (KDC).
The KerberosServiceKDC is used to specify the service Kerberos KDC when using cross-realm Kerberos authentication.
In most cases, a single realm and KDC machine are used to perform the Kerberos authentication, which means that this property would not be required. However, the property is available for complex setups where a different realm and KDC machine are used to obtain an authentication ticket (AS request) and a service ticket (TGS request).
Specifies the full file path to an MIT Kerberos credential cache file.
Set this property if you want to use a credential cache file that was created using the MIT Kerberos Ticket Manager or kinit command.
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.
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.
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. |

| XMLBLOB | The certificate store is a string that contains a certificate in XML format. |
| 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.
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.
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.
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.
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. |

| 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.
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.
Note: By default, the Sync App connects to the system proxy. To disable this behavior and connect to one of the following proxy types, set ProxyAutoDetect to false.
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 Apache HBase. Traffic flows back and forth via the proxy at this location. |
| SOCKS4 | 1080 | The port where the Sync App opens a connection to Apache HBase. 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 Apache HBase. If the SOCKS 5 proxy requires authentication, set FirewallUser and FirewallPassword to credentials the proxy recognizes. |
To connect to HTTP proxies, use ProxyServer and ProxyPort. To authenticate to HTTP proxies, use ProxyAuthScheme, ProxyUser, and ProxyPassword.

Specifies whether the provider checks your system proxy settings for existing proxy server configurations, rather than using a manually specified proxy server.
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.
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.
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.
Supported authentication types :
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.
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.
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.
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.
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.
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.
The available modules and submodules are:
| Module Name | Module Description | Submodules |
| INFO | General Information. Includes the connection string, product version (build number), and initial connection messages. |
|
| EXEC | Query Execution. Includes execution messages for user-written SQL queries, parsed SQL queries, and normalized SQL queries. Success/failure messages for queries and query pages appear here as well. |
|
| HTTP | HTTP protocol messages. Includes HTTP requests/responses (including POST messages), as well as Kerberos related messages. |
|
| WSDL | Messages pertaining to the generation of WSDL/XSD files. | — |
| SSL | SSL certificate messages. |
|
| AUTH | Authentication related failure/success messages. |
|
| SQL | Includes SQL transactions, SQL bulk transfer messages, and SQL result set messages. |
|
| META | Metadata cache and schema messages. |
|
| FUNC | Information related to executing SQL functions. |
|

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 . |
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.
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\\ApacheHBase 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 .
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 .
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 .
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.
This section provides a complete list of the Miscellaneous properties you can configure in the connection string for this provider.
| Property | Description |
| ColumnEncoding | The Encoding used for the column values. Accepted entries are None, UTF8, and BASE64. None is the default. |
| DatetimeFormat | The format used when inserting datetime values into the database. |
| ExposeColumnTimestamp | Specifies whether to expose the cell timestamp as a separate column when executing the SELECT Statement. |
| IncludeDisabledTables | Specifies whether to retrieve disabled tables. |
| 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. |
| Pagesize | Specifies the maximum number of records per page the provider returns when requesting data from Apache HBase. |
| PseudoColumns | Specifies the pseudocolumns to expose as table columns, expressed as a string in the format 'TableName=ColumnName;TableName=ColumnName'. |
| ResetTableMetadataOnDelete | Specifies whether to reset the cache table after executing the DELETE Statement. |
| RetrieveSelectedColumnsOnly | Specifies whether to retrieve selected columns only when executing a SELECT statement. |
| RowScanDepth | The maximum number of rows to scan to look for the columns available in a table. |
| ScannerCaching | Specify a scanner cache that will be filled before the Scan result is returned, setting setCaching to the number of rows to cache before returning the result. By default, the caching setting on the table is used. The goal is to balance IO and network load. |
| Timeout | Specifies the maximum time, in seconds, that the provider waits for a server response before throwing a timeout error. |
| TypeDetectionScheme | Determines how to determine the data type of columns. |
| UserDefinedViews | Specifies a filepath to a JSON configuration file that defines custom views. The provider automatically detects and uses the views specified in this file. |
| UseSQLFiltering | Specifies whether to use the ScannerFilter when executing the SELECT Statement. |
The Encoding used for the column values. Accepted entries are None, UTF8, and BASE64. None is the default.
This field is used to encode the column value. Use the following options to specify your column encoding:
The format used when inserting datetime values into the database.
This can be used to automatically format any datetime values entering a database.
Specifies whether to expose the cell timestamp as a separate column when executing the SELECT Statement.
The column name consists of the name of the cell and a fixed suffix
Specifies whether to retrieve disabled tables.
Specifies whether to retrieve disabled tables.
Specifies the maximum number of rows returned for queries that do not include either aggregation or GROUP BY.
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.
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.
| 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. |
Specifies the maximum number of records per page the provider returns when requesting data from Apache HBase.
When processing a query, instead of requesting all of the queried data at once from Apache HBase, the Sync App can request the queried data in pieces called pages.
This connection property determines the maximum number of results that the Sync App requests per page.
Note: Setting large page sizes may improve overall query execution time, but doing so causes the Sync App to use more memory when executing queries and risks triggering a timeout.
Specifies the pseudocolumns to expose as table columns, expressed as a string in the format 'TableName=ColumnName;TableName=ColumnName'.
This property allows you to define which pseudocolumns the Sync App exposes as table columns.
To specify individual pseudocolumns, use the following format:
Table1=Column1;Table1=Column2;Table2=Column3
To include all pseudocolumns for all tables use:
*=*
Specifies whether to reset the cache table after executing the DELETE Statement.
Specifies whether to reset the cache table after executing the DELETE Statement.
Specifies whether to retrieve selected columns only when executing a SELECT statement.
By default, the Sync App will create a generic scanner to retrieve the results from HBase. This enables all values to be returned without HBase filtering out rows containing empty columns that were selected.
When set to 'True', the Sync App will only retrieve the selected columns from HBase. Note in this scenario, HBase will not return rows where a selected column is empty. In such a case, this can cause a different number of rows to be returned for various queries. This setting can improve performance but it should only be used when you know that there are no empty values for the selected columns or in the case that you don't want these rows to be returned.
The maximum number of rows to scan to look for the columns available in a table.
The columns in a table must be determined by scanning table rows. This value determines the maximum number of rows that will be scanned.
Setting a high value may decrease performance. Setting a low value may prevent the data type from being determined properly, especially when there is null data.
Specify a scanner cache that will be filled before the Scan result is returned, setting setCaching to the number of rows to cache before returning the result. By default, the caching setting on the table is used. The goal is to balance IO and network load.
It means there is no cache for the scanner if it is less than or equal to 0. A suitable cache value can improve query efficiency, but it can also introduce additional memory usage.
Specifies the maximum time, in seconds, that the provider waits for a server response before throwing a timeout error.
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.
Determines how to determine the data type of columns.
| None | Setting TypeDetectionScheme to None will return all columns as strings. The RowScanDepth determines the number of rows to be scanned to retrieve the column listing. |
| RowScan | Setting TypeDetectionScheme to RowScan will scan rows to heuristically determine the data type. The RowScanDepth determines the number of rows to be scanned to retrieve the column listing and column data type. |
Specifies a filepath to a JSON configuration file that defines custom views. The provider automatically detects and uses the views specified in this file.
UserDefinedViews allows you to define and manage custom views through a JSON-formatted configuration file called UserDefinedViews.json. These views are automatically recognized by the Sync App and enable you to execute custom SQL queries as if they were standard database views. The JSON file defines each view as a root element with a child element called "query", which contains the SQL query for the view.
For example:
{
"MyView": {
"query": "SELECT * FROM Account WHERE MyColumn = 'value'"
},
"MyView2": {
"query": "SELECT * FROM MyTable WHERE Id IN (1,2,3)"
}
}
You can use this property to define multiple views in a single file and specify the filepath.
For example:
UserDefinedViews=C:\Path\To\UserDefinedViews.jsonWhen you specify a view in UserDefinedViews, the Sync App only sees that view.
For further information, see User Defined Views.
Specifies whether to use the ScannerFilter when executing the SELECT Statement.
If UseSQLFiltering = false, only the client filter will be used.

NSIS 3.10
Copyright (C) 1999-2025 Contributors THE ACCOMPANYING PROGRAM IS PROVIDED UNDER THE TERMS OF THIS COMMON PUBLIC LICENSE ("AGREEMENT"). ANY USE, REPRODUCTION OR DISTRIBUTION OF THE PROGRAM CONSTITUTES RECIPIENT'S ACCEPTANCE OF THIS AGREEMENT.
1. DEFINITIONS
"Contribution" means:
a) in the case of the initial Contributor, the initial code and documentation distributed under this Agreement, and b) in the case of each subsequent Contributor:
i) changes to the Program, and
ii) additions to the Program;
where such changes and/or additions to the Program originate from and are distributed by that particular Contributor. A Contribution 'originates' from a Contributor if it was added to the Program by such Contributor itself or anyone acting on such Contributor's behalf. Contributions do not include additions to the Program which: (i) are separate modules of software distributed in conjunction with the Program under their own license agreement, and (ii) are not derivative works of the Program.
"Contributor" means any person or entity that distributes the Program.
"Licensed Patents " mean patent claims licensable by a Contributor which are necessarily infringed by the use or sale of its Contribution alone or when combined with the Program.
"Program" means the Contributions distributed in accordance with this Agreement.
"Recipient" means anyone who receives the Program under this Agreement, including all Contributors.
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
b) its license agreement:
i) effectively disclaims on behalf of all Contributors all warranties and conditions, express and implied, including warranties or conditions of title and non-infringement, and implied warranties or conditions of merchantability and fitness for a particular purpose;
ii) effectively excludes on behalf of all Contributors all liability for damages, including direct, indirect, special, incidental and consequential damages, such as lost profits;
iii) states that any provisions which differ from this Agreement are offered by that Contributor alone and not by any other party; and
iv) states that source code for the Program is available from such Contributor, and informs licensees how to obtain it in a reasonable manner on or through a medium customarily used for software exchange.
When the Program is made available in source code form:
a) it must be made available under this Agreement; and
b) a copy of this Agreement must be included with each copy of the Program.
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.
