Subject [jira] [Commented] (CASSANDRA-8730) Optimize UUIDType comparisons
Date Fri, 06 Feb 2015 21:28:35 GMT

    [ https://issues.apache.org/jira/browse/CASSANDRA-8730?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=14309953#comment-14309953

J.B. Langston commented on CASSANDRA-8730:
------------------------------------------

Hmm, setting my clock back didn't help. I still got the same results as before. I'm not sure
why it did not compact away almost half the data before.

> Compaction is slow on tables using compound keys containing UUIDs due to being CPU bound
by key comparison.  [~benedict] said he sees some easy optimizations that could be made for
UUID comparison.
