Ted Yu commented on HBASE-14969:
--------------------------------
For NoLimitThroughputController :
{code}
44 private volatile boolean stopped;
{code}
Does the field have to be volatile ?
I don't see synchronization around access to the field.
{code}
33 * <li>In normal case, the max throughput is tune between
{code}
'is tune' -> 'is tuned'
> Add throughput controller for flush

> 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.
