Subject [jira] [Commented] (HBASE-11165) Scaling so cluster can host 1M regions and beyond (50M regions?)
Date Fri, 15 Aug 2014 18:43:20 GMT

    [ https://issues.apache.org/jira/browse/HBASE-11165?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=14098910#comment-14098910

Andrew Purtell commented on HBASE-11165:
----------------------------------------

bq. Guys, I'd like to start the discussion on splitting meta (HBASE-11288). As our experiments
shows splitting is a must for scaling. Thoughts?

As long as lower scale deploys don't run into potential new issues with a split meta in 0.98,
we could be good, i.e. disabled by default in 0.98, enabled by default in later versions.

> This discussion issue comes out of "Co-locate Meta And Master HBASE-10569" and comments
on the doc posted there.
> A user -- our Francis Liu -- needs to be able to scale a cluster to do 1M regions maybe
even 50M later.  This issue is about discussing how we will do that (or if not 50M on a cluster,
how otherwise we can attain same end).
> More detail to follow.
