   Learning more about this every day, but it looks like the memory options (writeBufferSize - the mem_table, block cache, etc.) are per column family anyway and therefore per Flink state and *not* per keyed operator and *not* globally, even after this PR.
   
   @StefanRRichter to me it looks like this "only" affects the number of compaction threads (previously `x per keyed operator`, with this PR `x per TM`) and maybe some configuration properties that are shared with this PR. What else does this affect?
