[jira] [Commented] (HBASE-8329) Limit compaction speed

["Jean-Daniel Cryans (JIRA)" <ji...@apache.org>]

    [ https://issues.apache.org/jira/browse/HBASE-8329?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=13904652#comment-13904652 ] 

Jean-Daniel Cryans commented on HBASE-8329:
-------------------------------------------

[~sershe] Looking back at my unread emails I found that I didn't reply to your latest request so here it is.

PeakCompactionsThrottle could use some more complete javadoc, also it might be good to note somewhere that we're limiting speed _per_ compaction, not RS-wide. Bumping up the number of concurrent compaction handlers won't make throttling more aggressive. Could be counter-intuitive for some folks.

Also this comment has an extra white space "Limit peak hour compaction speed , slow down when it is too fast."

Can be fixed on commit, +1.

> There is no speed or resource limit for compaction，I think we should add this feature especially when request burst.
