[jira] [Commented] (CASSANDRA-6202) Add a LOCAL_ONE consistency level

["Brandon Williams (JIRA)" <ji...@apache.org>]

    [ https://issues.apache.org/jira/browse/CASSANDRA-6202?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=13795576#comment-13795576 ] 

Brandon Williams commented on CASSANDRA-6202:
---------------------------------------------

A few quick notes from eyeballing it:

* cassandra.thrift version needs to be bumped.  To be safe, I think we need to regenerate.
* cql3 doc needs to be updated.
* probably ought to add a unit test, since I'm not sure how we could easily detect a cross-dc read in a dtest.

> There are an increasing amount of use cases where ONE is desirable, but cross-DC traffic is not.  LOCAL_ONE would solves this by reading at ONE, but only within the DC the coordinator is in.
