Rules and Guidelines for Full Pushdown Optimization

Rules and Guidelines for Full Pushdown Optimization

Consider the following rules and guidelines when you configure full pushdown optimization:
  • The Data Integration Service can push all transformation logic in the mapping to IBM DB2, Oracle, Microsoft SQL Server, and ODBC sources such as Teradata, Greenplum, Netezza, and SAP HANA.
  • When you configure full pushdown optimization for a mapping with an Update Strategy transformation, you can use the Update else Insert strategy only for Oracle and Teradata.
