To optimize a mapping, add the mapping to a task, and then configure
SQL ELT optimization
 in the

Before you configure
SQL ELT optimization
, complete the following tasks:
  • Download and configure the database-specific ODBC drivers on Windows or Linux on the Secure Agent machine.
  • In
    Data Integration
    , select the appropriate ODBC subtype, such as Azure DW, DB2, Google BigQuery, Redshift, PostgreSQL, Snowflake, or Teradata in the ODBC connection properties.
  • To configure
    SQL ELT optimization
     to any other supported databases, for example, Microsoft Access or Netezza, select the
    ODBC subtype
     as
    Other
     in the ODBC connection properties.
  • If you connect to Netezza or Teradata from Linux, you must select
    Data Direct
     as the
    Driver Manager for Linux
     in the ODBC connection properties.
Configure source or full
SQL ELT optimization
