Subject [jira] [Commented] (HBASE-11165) Scaling so cluster can host 1M regions and beyond (50M regions?)
Date Tue, 20 May 2014 19:24:38 GMT

    [ https://issues.apache.org/jira/browse/HBASE-11165?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=14003857#comment-14003857

Andrew Purtell commented on HBASE-11165:

bq. If we are lazily allocating mslabs also then we could trigger GC activity as those are
large objects.
Gc-ing mslabs should be fast, since they're few large (2mb) objects?

No, I meant that allocating a large object could trigger GC that wouldn't otherwise have happened
at that time.

> 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.
