Subject [jira] [Commented] (HBASE-3743) Throttle major compaction
Date Mon, 25 Jun 2012 13:11:43 GMT

    [ https://issues.apache.org/jira/browse/HBASE-3743?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=13400453#comment-13400453

Lars George commented on HBASE-3743:

+1 on a feature like that. We need some script/tool/thread that can run major compactions
based on load and abort if the load goes over a certain threshold. Once the low load is resumed
we can continue where left off. Do this region by region, with a configurable number, i.e.
one per cluster, one per node, and so on.

We should also add a JMX/API call that returns the compaction status per server. It should
list the various compaction queues, live compactions, their scope, and region/cf they work
on. Maybe put this into the ServerInfo?

> For those use cases when a stop-the-world approach is not practical, it is useful to
be able to throttle the impact that major compaction has on the cluster.
