However, the thread-safeness of > the in-memory flush of CompactingMemStore is based on taking the region's > updateLock. > The in-memory flush can be skipped in the replay time (anyway everything is > flushed to disk just after the replay). Therefore it is acceptable to just > skip the in-memory flush action while the updates come as part of replay from > WAL. -- This message was sent by Atlassian JIRA (v6.3.15#6346)
