> Add throughput controller for flush

> Key: HBASE-14969
> URL: https://issues.apache.org/jira/browse/HBASE-14969
> Project: HBase

>
> 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.
