-----------------------------------------------
@Chunhui
bq.(meaning that while one thread flushes, the others are blocking the inserts
and not flushing)
The above is one of JD's comments. Currently the patch tries to make more
flushes concurrently. So in startCacheFlush we will now be blocking the
incoming writes more right?
As more flush threads will try getting the updatesLock.writeLock. I may be
wrong here. Pls correct me..Thanks..
