Transformer Stage
Posted: Mon Nov 16, 2009 1:35 am
Hi,
I believe the Transformer stages are haevy compared to other stages like Copy or Modify etc. Has this changed in IBM InfoSphere DataStage?
In the "Parallel Job Advanced User Guid(7.5.1)", it is written that we shoud use transformer stages sparingly and use other stages such as filter stage, Switch Stage and modify Stage.
However, in the IBM Redbook ""IBM InfoSphere DataStage Data Flow and Job Design", it is written "Use the parallel Transformer stage (not the BASIC Transformer) instead of
the Filter or Switch stages"
Am i missing the context over here or In 8 Transformer stages are lighter then other versions whne compared to switch or filter or copy?
Can any of you please explain as they appear to be contradicting each other?
Regards,
Sai
