    • In order to use a scheduling strategy which is more similar to the pre FLIP-6 behaviour where Flink tries to spread out the workload across all available `TaskExecutors`, one needs to set `cluster.evenly-spread-out-slots: true` in the `flink-conf.yaml`

    Description

      With Flip-6, we changed the default behaviour how slots are assigned to TaskManagers. Instead of evenly spreading it out over all registered TaskManagers, we randomly pick slots from TaskManagers with a tendency to first fill up a TM before using another one. This is a regression wrt the pre Flip-6 code.

      I suggest to change the behaviour so that we try to evenly distribute slots across all available TaskManagers by considering how many of their slots are already allocated.
