Subject [jira] [Updated] (HBASE-14969) Add throughput controller for flush
Date Thu, 28 Dec 2017 17:56:59 GMT

     [ https://issues.apache.org/jira/browse/HBASE-14969?page=com.atlassian.jira.plugin.system.issuetabpanels:all-tabpanel
]

stack updated HBASE-14969:
--------------------------
    Release Note: Adds means of throttling flush throughput. By default there is no limit;
we use NoLimitThroughputController. An alternative controller, PressureAwareFlushThroughputController,
allows specifying throughput bounds. A new simple factor, flush pressure, influences throughput.
See PressureAwareFlushThroughputController.java class for detail.

> 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.
