-----------------------------

             Summary: Add throughput controller for flush
                 Key: HBASE-14969
                 URL: https://issues.apache.org/jira/browse/HBASE-14969
             Project: HBase
          Issue Type: Improvement
    Affects Versions: 2.0.0
            Reporter: Yu Li
            Assignee: Yu Li


In HBASE-8329 we added a throughput controller for compaction, to avoid spike caused by huge
IO pressure like network/disk overflow. However, even with this control on, we are still observing
disk utils near 100%, and by analysis we think this is caused by flush, especially when we
increase the setting of {{hbase.hstore.flusher.count}}

In this JIRA, we propose to add throughput control feature for flush, as a supplement of HBASE-8329
to better control IO pressure.
