Ted Yu commented on HBASE-4528:
-------------------------------

Minor suggestion for the new MemStore.remove() method:
Since it is called only in case of error recovery, I feel a better name maybe rollback().

> This allows for better throughput when there are hot rows. A single row update improves from 100 puts/sec/server to 5000 puts/sec/server.
