Yu Li commented on HBASE-17507:
-------------------------------
According to our study and prototype here, mvcc preassign will be some kind of
limitation when we try to parallelize WAL sync (IO bound) and mvcc assigning
(CPU bound) on write path, so let's just keep it configurable for a little bit
longer (smile).
