Sylvain Lebresne commented on CASSANDRA-4217:
---------------------------------------------
One slight advantage of writetime over either updatetime or inserttime is that
it doesn't suggest that it's the time of update or insert "in the sense of
SQL". But that's a minor detail I guess, and again I'm fine going with whatever
others prefer, just wanted to mention it.
> Easy access to column timestamps (and maybe ttl) during queries

> 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)
