Subject [jira] [Commented] (PHOENIX-4531) Delete on a table with a global mutable index can issue client-side deletes against the index
Date Thu, 18 Jan 2018 20:59:00 GMT

    [ https://issues.apache.org/jira/browse/PHOENIX-4531?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=16331217#comment-16331217
] 

James Taylor commented on PHOENIX-4531:
---------------------------------------

Attached v2 patch with more comments and some cleanup to code that determines the update count
returned to the client. Looks like our pre-commit is busted (or on vacation). I suspect it's
due to the move to HBase 1.4 on master (but it could be coincidence).

Please review, [~vincentpoon].

> For a table with a global mutable index, I found the following result in client-side
deletes against both the data table and index table.
> "DELETE FROM data_table" 
> "DELETE FROM data_table WHERE indexed_col='v'"
> We only need the delete to be issued against the data table, because
> 1) It's redundant since a delete against the index will be issued on the server side
when we process the delete of the data table row
> 2) Deletes issued from the client-side won't have the index failure policy
