Subject [jira] [Commented] (CASSANDRA-8730) Optimize UUIDType comparisons
Date Fri, 06 Feb 2015 21:49:35 GMT

    [ https://issues.apache.org/jira/browse/CASSANDRA-8730?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=14309991#comment-14309991
] 

Aleksey Yeschenko commented on CASSANDRA-8730:
----------------------------------------------

[~jblangston@datastax.com] What's your schema? Does it use 'uuid' or 'timeuuid'? b/c the patch
in its current form does only optimize 'uuid'.

> 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.
