You can use the Informatica Connector Toolkit to configure pushdown logic for a connector to push transformation logic to source or target databases for processing using the native connection.
You can specify the following pushdown types for a connector:
Full
A pushdown logic where the task pushes as much of the transformation logic as possible to the target database.
Source
A pushdown logic where the task pushes down as much as the transformation logic as possible to process in the source database. When you select source pushdown optimization, the task pushes the transformation logic for all the supported transformations downstream in the mapping.
The Informatica Connector Toolkit currently does not implement the source pushdown logic for a connector.
