Subject [jira] [Commented] (PHOENIX-3818) Add client setting to disable server side UPSERT SELECT work
Date Tue, 02 May 2017 17:34:04 GMT

    [ https://issues.apache.org/jira/browse/PHOENIX-3818?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=15993355#comment-15993355

James Taylor commented on PHOENIX-3818:
---------------------------------------

The run on server side code I mentioned above has been in the code base since our 1.0 release.
Removing this would be a regression.

Even the new feature introduced in PHOENIX-3271 was to improve scaling. It's not scalable
to run a big UPSERT SELECT that returns all data back to a single client. IMHO, having a way
to disable this is not particularly valuable. I'd be more inclined to spend the time perf
testing any scenarios folks are worried about.

> PHOENIX-3271 introduced RS -> RS RPCs by default via UPSERT SELECT statements. Add
a client side setting that disables this behavior.
