In addition to Kapil's answer, You can have "push down"
optimization at source database or target database or Full
(Source and target). But before you enable this option you
keep the following things in mind

1. When you are processing long transaction at database
level , The objects will be lock and data base objects are
not available for other operations for long time.

2. It will inturn hampers the datbase concurrency and
increases the chance of "Dead locks" on database

Thanks : Satya

Answer / kapil

The Pushdown Optimization Option improves performance by
enabling processing to be “pushed down” to a
relational database, maximizing fl exibility, minimizing
unnecessary data movement, and providing the optimal
performance for both data-intensive and process-intensive
transformations.

Give one example for each of conditional aggregation, non-aggregate expression, and nested aggregation?
