Subject [jira] [Commented] (CASSANDRA-8730) Optimize UUIDType comparisons
Date Fri, 18 Sep 2015 00:50:04 GMT

    [ https://issues.apache.org/jira/browse/CASSANDRA-8730?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=14804770#comment-14804770

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

bq. any chance to see this patched in 2.0 branch?

2.0 line has officially been declared EOL, and the next release (2.0.17) is going to be the
final one.

You could apply the patch manually though and build from source.

> 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.
