Subject [jira] [Commented] (HBASE-7213) Have HLog files for .META. edits only
Date Thu, 29 Nov 2012 19:54:58 GMT

    [ https://issues.apache.org/jira/browse/HBASE-7213?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=13506730#comment-13506730
] 

Todd Lipcon commented on HBASE-7213:
------------------------------------

I agree it seems to make sense to lump this with the multi-WAL work. Perhaps an interface
like "WALFactory" or "WALProvider", which, given a region name, gives back a WAL instance?
The basic implementation would always provide the single WAL. Then, we could add the feature
that returns a different WAL for META alone. More complex implementations could choose to
give different tenants of a cluster separate WALs, etc.

> Over on HBASE-6774, there is a discussion on separating out the edits for .META. regions
from the other regions' edits w.r.t where the edits are written. This jira is to track an
implementation of that.
