> Current implementation of a optimized rebalancing with disabled WAL used when
> all local partitions are MOVING and persistence is enabled has multiple flaws:
> # There are races between concurrent topology change and partition owning
> after a checkpoint causing consistency issues.
> # Partitions will not be owned after a topology has changed and new topology
> version is compatible with previous.
> This is the reason for flaky tests [1] [2]
