Teradata as Target

Data Source Solutions DSS supports integrating changes into Teradata location. This section describes the configuration requirements for integrating changes (using Integrate and Refresh) into Teradata location. For the list of supported Teradata versions, into which DSS can integrate changes, see Integrate changes into location in Capabilities. DSS also allows you to perform Compare for Teradata database in source location.

DSS uses the Teradata ODBC driver to write data to Teradata during Continuous Integrate and Row-wise Refresh.

DSS uses the TPT Load interface for copying data into the Teradata tables during Bulk Refresh and the TPT Stream/Upload interface for loading data into the burst table during Burst Integrate.

The preferred methods for writing data to Teradata are using Burst Integrate and Bulk Refresh as they provide better performance.

Grants for Integrate and Refresh

This section lists the grants required for integrating changes into Teradata. By default, the DSS User has all required permissions to Integrate changes into default user database.

  1. To create target tables using Refresh, the DSS database User must be granted <b>create table</b> and <b>drop table</b> privileges.

    grant create table, drop table on <em>targetdb</em> to <em>username</em>;
    
  2. To change tables that are owned by other users (using action TableProperties with parameter Schema), the DSS database User must be granted <b>select</b>, <b>insert</b>, <b>update</b>, and delete privileges.

    grant select, insert, update, delete on <em>targetdb</em> to <em>username</em>;
    
  3. To perform Burst Integrate and Bulk Refresh, the DSS database User must be granted <b>create macro</b> and drop macro privileges.

    grant create macro, drop macro on <em>targetdb</em> to <em>username</em>;
    
  4. (Optional) To use a custom BurstTableSchema, the target schema must be granted the following privilege:

    grant select on <em>burst_table_schema</em> to <em>target_schema</em> with grant option;
