[jira] [Created] (FLINK-25921) Support different input parallelism for preCommit topology

Fabian Paul created FLINK-25921:
-----------------------------------

             Summary: Support different input parallelism for preCommit topology
                 Key: FLINK-25921
                 URL: https://issues.apache.org/jira/browse/FLINK-25921
             Project: Flink
          Issue Type: Sub-task
          Components: API / DataStream
    Affects Versions: 1.15.0, 1.16.0
            Reporter: Fabian Paul


Currently, we assume that the pre-commit topology has the same parallelism as the operator before when inserting the failover region. To support a different parallelism we might need to insert a different identity map to customize the mapping.
