Subject [jira] [Commented] (PHOENIX-3128) Remove extraneous operations during upsert with local immutable index
Date Tue, 02 Aug 2016 14:06:20 GMT

    [ https://issues.apache.org/jira/browse/PHOENIX-3128?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=15404034#comment-15404034

Rajeshbabu Chintaguntla commented on PHOENIX-3128:
--------------------------------------------------

The patch looks fine [~jamestaylor]. 
bq. It shouldn't be necessary to send the local index mutations from the client. We can perhaps
leave this for 4.8.1
Yes it's better not to send the local index mutations from client. Fine to leave for 4.8.1.

> 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.
