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

             Summary: Introduce framework off heap memory config
                 Key: FLINK-14637
                 URL: https://issues.apache.org/jira/browse/FLINK-14637
             Project: Flink
          Issue Type: Sub-task
          Components: Runtime / Task
            Reporter: Andrey Zagrebin
             Fix For: 1.10.0


At the moment after [-FLINK-13982-|https://issues.apache.org/jira/browse/FLINK-13982], when we do not account for adhoc direct memory allocations for Flink framework (except network buffers) or done by some used libraries used in Flink. In general, we expect this allocations to stay under a certain reasonably low limit but we have to have some margin for them so that JVM direct memory limit is not exactly equal to network buffers and does not fail. We can address it by introducing framework off heap memory config option.
