[jira] [Created] (HBASE-14969) Add throughput controller for flush
Yu Li created HBASE-14969:
-----------------------------
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.
