Subject [jira] [Commented] (HBASE-10943) Backport HBASE-7329 to 0.94

    [ https://issues.apache.org/jira/browse/HBASE-10943?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=13966206#comment-13966206

Liu Shaohui commented on HBASE-10943:
-------------------------------------

[~lhofhansl]
According the discussion in HBASE-6980, the flush marker is not necessary now and removing
flush marker will not introduce any compatibility issues.

The main changes in HBASE-7329 is:
a, remove the flush marker in completeCacheFlush
b, bring a oldestSeqNumsLock to protect lastSeqWritten  and make locking more granular

I think this issue is depended on HBASE-8752. And parallel region flush be benefit to write
heavy workload.
