You can specify custom objects to help you design parallel jobs
that transform or cleanse data.
You can define these types of object:
Parallel routines
Custom Parallel stage types
QualityStage objects
Parallel routines
Parallel jobs can execute routines before or after a processing
stage executes (a processing stage being one that takes input, processes
it then outputs it in a single stage), or can use routines in expressions
in Transformer stages.
Custom stages for parallel jobs
In addition to the wide range of parallel stage types available,
the Designer allows you to define your own stage types, which you
can then use in parallel jobs.
