[jira] [Commented] (CASSANDRA-7925) TimeUUID LSB should be unique per process, not just per machine

["T Jake Luciani (JIRA)" <ji...@apache.org>]

    [ https://issues.apache.org/jira/browse/CASSANDRA-7925?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=14544229#comment-14544229 ] 

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

Seems like we should have an lsb per thread.  If a client or server generates a uuid at the same clocktime we want these to be unique within the process.

Updated patch here. Using Sigar to get the pid. https://github.com/tjake/cassandra/tree/7925-timeuuidlsb

> a sufficient solution would be to include references to pid and classloader within lsb.
