> 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.
