Subject [jira] [Commented] (HBASE-7055) port HBASE-6371 tier-based compaction from 0.89-fb to trunk (with changes)

    [ https://issues.apache.org/jira/browse/HBASE-7055?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=13687416#comment-13687416

Sergey Shelukhin commented on HBASE-7055:
-----------------------------------------

we chatted during HBaseCon with [~liyin]. The main issue blocking this JIRA is lack of configuration
documentation, my attempts to come up with realistic scenarios and configs with lots of improvement
on test EC2 clusters were not very successful (and also take a while to actually have a chance
to see the policy taking effect). Clearly certain read/data patterns are needed. We may get
some configuration guidelines from FB guys, then we can incorporate them into book and commit
this.

Do you want to file separate JIRA for versions?
