Subject [jira] [Commented] (CASSANDRA-7919) Change timestamp representation to timeuuid
Date Sat, 13 Sep 2014 03:23:34 GMT

    [ https://issues.apache.org/jira/browse/CASSANDRA-7919?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=14132501#comment-14132501

Benedict commented on CASSANDRA-7919:
-------------------------------------

I'm also a little uncomfortable making it explicitly a TimeUUID at the client level, since
this may mean clients start expecting the exact TimeUUID back with each request also. This
would definitely be a bad thing, and prevent almost all of the timestamp optimisation work
we have pencilled for 3.0, as we would have to retain its full bytes forever, which are half
random, the state space of which will grow linearly with cluster up-time.

> In order to overcome some of the issues with timestamps (CASSANDRA-6123) we need to migrate
to a better timestamp representation for cells.
> Since drivers already support timeuuid it makes sense to migrate to this internally (see
CASSANDRA-7056)
