[jira] [Commented] (CASSANDRA-7296) Add CL.COORDINATOR_ONLY

    [ https://issues.apache.org/jira/browse/CASSANDRA-7296?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=14245489#comment-14245489 ] 

Jon Haddad commented on CASSANDRA-7296:
---------------------------------------

I suspect this would help with Spark since it currently has to do 1 query per token range.  Kind of a mess doing 256 queries that all look at the same sstables.

> For reasons such as CASSANDRA-6340 and similar, it would be nice to have a read that never gets distributed, and only works if the coordinator you are talking to is an owner of the row.
