Anoop Sam John commented on HBASE-7869:
---------------------------------------
[~ram_krish] New config item may not be needed. When
hbase.regionserver.optionallogflushinterval is set as 0, means you need an
immediate sync for all the operations. The thread is starting for the deferred
sync. So in this case thread wont be useful at all and so dont start it at all.
Yes at the close() time no need to go for the thread close part and join.
> Provide way to not start LogSyncer thread

> In our usecase we want all the Mutations on all the tables to be immediately
> written and synced to WAL. We dont want the LogSyncer thread to be running in
> such a case.
> In minbatch operation we write entries to WAL and we use postWALWrite and
> write some more WAL entries(Only write no sync). We want all these written
> data to be synced as one unit (at the sync step in doMiniBatchOperation) But
> if the LogSyncer thread is running in the system it can come and do the sync
> at any point in time which we dont want in our case.
