Subject [jira] [Commented] (HBASE-7213) Have HLog files for .META. edits only
Date Thu, 29 Nov 2012 23:10:59 GMT

    [ https://issues.apache.org/jira/browse/HBASE-7213?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=13506923#comment-13506923
] 

Devaraj Das commented on HBASE-7213:
------------------------------------

[~tlipcon], good points there. But I'd like to separate the META SPOF work from the full fledged
multiwal work (for the full multi-wal case, we'd need to fix up things like replication, and
those can be skipped from the meta-only design that this jira attempts to do).
[~yuzhihong@gmail.com], I guess you are right. In theory, one could read the HLogFactory as
the WALFactory... 

Thoughts? (i am in the process of extending the patch I previously posted to a fully functional
one)

> 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.
