[jira] [Commented] (HBASE-19967) Add Major Compaction Tool options
for off-peak / on-peak hours
[ https://issues.apache.org/jira/browse/HBASE-19967?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=16504131#comment-16504131 ]
Xu Cang commented on HBASE-19967:
---------------------------------
[~apurtell]
I am trying to understand your description better. Are you suggesting by defining off-peak range, this command line program can take w sets of arguments, and it makes the decision which set to use based on time?
Or are you suggesting to hook this configuration to PressureAwareCompactionController to control compaction's throughput?
Thanks,
Xu

> After HBASE-19528 an operator can disable automatic major compaction and more intelligently manage major compaction impact on cluster operations with an external tool that drives the compaction activity. This tool can be invoked at whatever interval is desirable, and can restrict activity by table and column family, with given concurrency of regionservers compacting at a given time.
> Add Major Compaction Tool options for off-peak / on-peak hours. Allow for definition of "off-peak" as a time range bounded by two points on a 24 hour clock, and for two concurrency target for global compaction activity, one for the off-peak interval, the other for the remainder.
