RE: What is the difference between the flows of 3 parallelisms
Parallelism's are of 3 types:

1. Component Parallelism: All program components runnings simultaneously on different data sets.


2. Pipeline Parallelism: All program components runnings simultaneously on same data sets. we can break the pipeline parallelism using all sort based components.

Ex: sort, sort within groups, AGG, Rollup, Join, etc.


3. Data Parallelism: Distributes data records into multiple locations using partition components.


Thanks,
