Subject [jira] [Commented] (CASSANDRA-7367) add cql function to create timeuuid from date
Date Wed, 11 Jun 2014 23:09:02 GMT


Sylvain Lebresne commented on CASSANDRA-7367:

My bad, I realize that the goal is inserts here. In that case, I'm not entirely fan of such
functions because it makes it very easy to create 2 timeuuid that conflicts while the goal
of timeuuid is to avoid that. It feels to me that creating a timeuuid from a date for something
else than a query is intrinsically wrong, hence my reluctance to add a function to make it

> creating timeuuids in cql is unwieldy. Adding a toTimeuuid() function to convert a date/time
to a time uuid.
> ie, 
> create table foo (key timeuuid primary key, value text);
> insert into foo (key, value) values (toTimeuuid('2009-12-16 19:26:29-0500'), 'hello');
