Sylvain Lebresne commented on CASSANDRA-6655:
---------------------------------------------
bq. though full partition deletions were not added to the memtable size, they
were accounted in currentOperations and wouldn't end up not flushing
Scratch that, it seems we don't take currentOperations in account to flush
anymore, so full partition deletions are also affected.
> Writing mostly deletes to a Memtable results in undercounting the table's
> occupancy so it may not flush
