             Project: Apache Apex Core
          Issue Type: New Feature

Hi,

I have a DAG A->B->C.

1. A is kafka input operator reading from 4 different topics configured with ONE_TO_ONE strategy. Thus creating 4 partitons of A.
2. B and C are configured to have parallel partitions w.r.t. their input port. Thus, currently both B, C have 4 partitions.

I am observing B significant latency in B operator. Thus, would like to have 2 partitions for B per partition of A. Since, application is latency intensive, I want to avoid unifiers as far as possible.

How to achieve this partitioning?
