> In the case of accumulated entries for the same table/partition, they should be processed one by one in ASC order of write_id's.
> However, to support multi-threaded processing in the Cleaner, we need to make sure that the entries from the same group are not processed concurrently by multiple threads. 
> One of the solutions that don't involve synchronization (check if already in flight, re-try when possible) would be to move the entries from the same group to the next Cleaner cycle.
