Answer / krish
One can push transformation logic to the source or target
database using pushdown optimization. The Integration
Service translates the transformation logic into SQL queries
and sends the SQL queries to the source or the target
database which executes the SQL queries to process the
transformations. The amount of transformation logic one can
push to the database depends on the database, transformation
logic, and mapping and session configuration. The
Integration Service analyzes the transformation logic it can
push to the database and executes the SQL statement
generated against the source or target tables, and it
processes any transformation logic that it cannot push to
the databas
there are some limitations to it like if we are using
variable port we can't do pushdown.
