> 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?
