-----------------------------------
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.
