Subject [jira] [Commented] (CASSANDRA-4217) Easy access to column timestamps (and maybe ttl) during queries
Date Thu, 03 May 2012 19:48:50 GMT

    [ https://issues.apache.org/jira/browse/CASSANDRA-4217?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=13267742#comment-13267742

Rick Shaw commented on CASSANDRA-4217:
--------------------------------------

Could this be the tipping point for a proposal to add functions to the CQL3 grammar and a
plugin mechanism to define function methods?

> It would be interesting to allow accessing the timestamp/ttl of a column though some
syntax like
> {noformat}
> SELECT key, value, timestamp(value) FROM foo;
> {noformat}
> and the same for ttl.
> I'll note that currently timestamp and ttl are returned in the resultset because it includes
thrift Column object, but adding such syntax would make our future protocol potentially simpler
as we wouldn't then have to care about timestamps explicitely (and more compact in general
as we would only return timestamps when asked)
