Subject [jira] [Commented] (PHOENIX-3818) Add client setting to disable server side UPSERT SELECT work
Date Tue, 02 May 2017 18:06:04 GMT

    [ https://issues.apache.org/jira/browse/PHOENIX-3818?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=15993418#comment-15993418

Andrew Purtell commented on PHOENIX-3818:
-----------------------------------------

Ok I am not advocating a regression. What I think we need is a configuration toggle that makes
a system with distributed UPSERT SELECT act like an earlier version without the capability.
As you know a perf test will not guarantee we find ourselves in a production incident that
needs fast remediation. Features that can produce cross server RPC and attendant issues need
an off switch to aid in recovery of stability. Just as a rule, IMHO

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