Subject Re: Throttle major compaction for version 1.1.2
Date Thu, 24 Jan 2019 04:17:03 GMT
I can see in branch 1.1 that CompactSplitThread does load a
CompactionThroughputController here [1], and it's possible to set
PressureAwareCompactionThroughputController [2] on
"hbase.regionserver.throughput.controller" property.
PressureAwareCompactionThroughputController defines additional
configurations to control, eventually slowing down, compaction throughput.

HStore also considers offpeak hours when creating the compaction request
[3]. Offpeak configurations then available would be
"hbase.offpeak.end.hour" and "hbase.offpeak.start.hour".
