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

             Summary: Tune default values for FLIP-49 TM memory configurations with real production jobs.
                 Key: FLINK-15145
                 URL: https://issues.apache.org/jira/browse/FLINK-15145
             Project: Flink
          Issue Type: Task
          Components: Runtime / Configuration
            Reporter: Xintong Song
             Fix For: 1.10.0


In release 1.10, with FLIP-49, we introduced significant changes to the TaskExecutor memory model and it's related configuration options / logics.

Since the model and configuration logics are changed, it is reasonable that we also change the default configuration values. Currently, the default values are set with the gut feelings and experiences from e2e tests. It would be good that we try and tune the configurations with some real production jobs, of various scales if possible, before exposing the configurations in the release.
