That's an impressive pull request, @StephanEwen! From a first glance, it
looks very well-thought-out. I would be glad to work on some of the remaining
issues like the config entries or MiniCluster tests. In addition, I would like
to add some nightly performance tests.
Is it fair to say that the off-heap memory doesn't add much value for
small-sized JVMs? So the default Flink execution mode will use heap memory and
one can switch to off-heap memory for setups with very large JVM heap memory
size.
