Subject [jira] [Commented] (PHOENIX-3128) Remove extraneous operations during upsert with local immutable index
Date Tue, 02 Aug 2016 13:54:20 GMT

    [ https://issues.apache.org/jira/browse/PHOENIX-3128?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=15403997#comment-15403997

James Taylor commented on PHOENIX-3128:
---------------------------------------

Any update, [~rajeshbabu]? It shouldn't be necessary to send the local index mutations from
the client. We can perhaps leave this for 4.8.1, as we really should get a new RC up. WDYT?

> Upsert to a table with a local immutable index is supposed to be more efficient than
to a table with a local mutable index, but it's actually slower (in our environment by 30%)
due to extraneous operations involved.
> The problem is twofold:
> 1. Client unnecessarily prepares and sends index update.
> 2. Index cleanup is done regardless of the immutability of the table.
