Subject [jira] [Commented] (HBASE-12522) Backport WAL refactoring to branch-1
Date Wed, 19 Nov 2014 00:07:34 GMT

    [ https://issues.apache.org/jira/browse/HBASE-12522?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=14217089#comment-14217089

Jesse Yates commented on HBASE-12522:
-------------------------------------

For the 'global' secondary index in Phoenix we could have a WAL for each region if we wanted
(or any combination up to the current impl). As long as we can still mess about with the stored
KVs, then we are ok (so we can replay them later and pull out the SI updates).

I think for the local indexes we don't need the bound either - its driven from the region-level
transactions on the same RS. But lets double check with [~jeffreyz]

> This will let us remove the Deprecated stuff in master, allow some baking time within
the 1.x line, and will give us the option of pulling back follow on performance improvements.
