--------------------------------

             Summary: Make TtlTimeProvider configurable when creating keyed state backend
                 Key: FLINK-16876
                 URL: https://issues.apache.org/jira/browse/FLINK-16876
             Project: Flink
          Issue Type: Improvement
          Components: Runtime / State Backends
    Affects Versions: 1.10.0
            Reporter: Yun Tang
             Fix For: 1.11.0


Currently, we would always use TtlTimeProvider.DEFAULT to create keyed state backend. This is somehow acceptable since we only support processing time for TTL now. However, this would make UT tests which would verify TTL logic not so convenient like FLINK-16581.

I propose to let TtlTimeProvider configurable when creating keyed state backend to not block other feature development.
