 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.
