Subject [jira] [Commented] (CASSANDRA-7925) TimeUUID LSB should be unique per process, not just per machine
Date Fri, 22 May 2015 14:17:18 GMT

    [ https://issues.apache.org/jira/browse/CASSANDRA-7925?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=14556184#comment-14556184
] 

T Jake Luciani commented on CASSANDRA-7925:
-------------------------------------------

I'm referring to the {{UUID getTimeUUID(long when)}} call.

It's currently used for paxos. 

Also, I imagine we will still allow the clients to specify timestamps (esp for thrift) in
CASSANDRA-7919 so the conversion to uuid would be on the server.

lsb collisions are also possible serverside.
> a sufficient solution would be to include references to pid and classloader within lsb.
