Subject [jira] [Commented] (CASSANDRA-7919) Change timestamp representation to timeuuid
Date Sat, 13 Sep 2014 02:38:34 GMT


Benedict commented on CASSANDRA-7919:

See my comments on CASSANDRA-6108 for details of why I don't think this is suitable. Since
we specifically want this for RAMP transactions we need guaranteed uniqueness cross-cluster,
which timeuuids only achieve if created _server side_. We will absolutely have to modify the
semantics of TimeUUID if we want them to be guaranteed unique still, at which point we may
as well consider the 64-bit representation I suggested on that ticket.

to a better timestamp representation for cells.
