             Summary: Investigate/improve tests stability when using InMemory Changelog implementation
                 Key: FLINK-26685
                 URL: https://issues.apache.org/jira/browse/FLINK-26685
             Project: Flink
          Issue Type: Improvement
          Components: Runtime / State Backends, Test Infrastructure
    Affects Versions: 1.15.0, 1.16.0
            Reporter: Roman Khachatryan
             Fix For: 1.16.0


Large scale tests often fail when using InMemory Changelog, either because of excessive GC pressure, serialization, or exceeding memory limits.

So far, it was fixed by using FS implementation on a case-by-case basis. Always using FS isn't straightforward.

Investigate if there are any ways to uniformly use FS impl. or stabilize in-memory impl.
