Subject [jira] [Commented] (HBASE-7055) port HBASE-6371 tier-based compaction from 0.89-fb to trunk
Date Wed, 07 Nov 2012 21:52:17 GMT

    [ https://issues.apache.org/jira/browse/HBASE-7055?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=13492737#comment-13492737

stack commented on HBASE-7055:
------------------------------

bq. Are we good with porting it without dynamic config updates, with cf-specific config stored
on CF, and off by default?

That could be good.  Do you think this new mechanism will be used?  Its objective is 'more
fine-grained control' according to the pdf Liyin just posted.  Have you tried it Sergey? 
Does it give good feedback if misconfigured?  Is this feature of any use if its not configurable
at runtime: i.e. does having to take the table offline to change a param make this improvement
moot until we have dynamic config?
