      Adds new flushing policy mechanism. Default, org.apache.hadoop.hbase.regionserver.FlushLargeStoresPolicy, will try to avoid flushing out the small column families in a region, those whose memstores are < hbase.hregion.percolumnfamilyflush.size.lower.bound. To restore the old behavior of flushes writing out all column families, set hbase.regionserver.flush.policy to org.apache.hadoop.hbase.regionserver.FlushAllStoresPolicy either in hbase-default.xml or on a per-table basis by setting the policy to use with HTableDescriptor.getFlushPolicyClassName().

    Description

      Currently the flush decision is made using the aggregate size of all column families. When large and small column families co-exist, this causes many small flushes of the smaller CF. We need to make per-CF flush decisions.
