Subject [jira] [Commented] (CASSANDRA-5582) Replace CustomHsHaServer with better oprtimized solution based on LMAX Disruptor.
Date Mon, 20 May 2013 20:49:17 GMT

    [ https://issues.apache.org/jira/browse/CASSANDRA-5582?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=13662349#comment-13662349
] 

Aleksey Yeschenko commented on CASSANDRA-5582:
----------------------------------------------

I tested pre-5530 trunk vs. Pavel's disruptor, and the difference was drastic. But yeah, not
TThreadedSelectorServer. Still sure it (disruptor-bases server) is gonna be faster, but some
new numbers on real hardware won't hurt. I'm gonna rerun the numbers as well, just in case.

> I have been working on https://github.com/xedin/disruptor_thrift_server and consider
it as stable and performant enough for integration with Cassandra. 
> Proposed replacement can work in both on/off Heap modes (depending if JNA is available)
and doesn't blindly reallocate things, which allows to resolve CASSANDRA-4265 as "Won't Fix".
