*Use sorted input in Aggretator transformation to decrease
the use of aggregate caches.If you use a Filter
transformation in the mapping, place the transformation
before the Aggregator transformation to reduce unnecessary
aggregation.
* We can use the Source Qualifier transformation to filter
as an alternate way to filter rows.
* Perform joins in a database when possible rather using a
joiner transform
*Adding an index to the columns used in a lookup condition
if you have privileges to modify the database containing a
lookup tables.
these are some simple techniques
