Hi Experts,

Performance Wise Which transformation is better in LOOKUP
AND JOINER TRansformations? Why? Can anybody please explain
it ?
Please help me out from this Question.

Thanks In Advance.

Answer Posted / sukanta

Look up will better perform because the cache is initially
created when the first record will reach at Look up
tarnsformation and the further records are work upon the
cached records.Look up will perfrom left outer Join
only.Other Joins can't be posible.You can check the records
are either exists in the lookup table or not.

Jioner will be slower than look up but sorted port
Join,well choosing of Master and detail configuration will
give better performance for Joiner.
