[jira] [Commented] (CASSANDRA-6237) Allow range deletions in CQL

["Tyler Hobbs (JIRA)" <ji...@apache.org>]

    [ https://issues.apache.org/jira/browse/CASSANDRA-6237?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=14118652#comment-14118652 ] 

Tyler Hobbs commented on CASSANDRA-6237:
----------------------------------------

It doesn't look like the patch handles multi-column relations.  We should definitely add support for that from the beginning.

There may be a fair amount of overlap with the logic for building slice ranges in SelectStatement, so make sure to reuse that if you can.

> We uses RangeTombstones internally in a number of places, but we could expose more directly too. Typically, given a table like:
> {noformat}
> CREATE TABLE events (
>     id text,
>     created_at timestamp,
>     content text,
>     PRIMARY KEY (id, created_at)
> )
> {noformat}
> we could allow queries like:
> {noformat}
> DELETE FROM events WHERE id='someEvent' AND created_at < 'Jan 3, 2013';
> {noformat}
