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

             Summary: MiniCluster use fixed network / managed memory sizes by defualt
                 Key: FLINK-15369
                 URL: https://issues.apache.org/jira/browse/FLINK-15369
             Project: Flink
          Issue Type: Improvement
          Components: Runtime / Configuration
            Reporter: Xintong Song
             Fix For: 1.10.0


Currently, Mini Cluster may allocate off-heap memory (managed & network) according to the JVM free heap size and configured off-heap fractions. This could lead to unnecessary large off-heap memory usage and unpredictable / hard-to-understand behaviors.

We believe a fix value for managed / network memory would be enough for a such a setup that runs Flink as a library.
