Subject [jira] Commented: (CASSANDRA-705) explore replacing socket nio with blocking io
Date Thu, 21 Jan 2010 02:28:54 GMT

    [ https://issues.apache.org/jira/browse/CASSANDRA-705?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=12803136#action_12803136
] 

Jonathan Ellis commented on CASSANDRA-705:
------------------------------------------

(3) I will code up the thread refactor then, I think that will deal with this problem.  Not
having to worry about packet size limitations is a pretty good reason to use TCP.  (Although
I haven't changed that yet, now that you mention it. :)

> MessagingService's nonblocking io has been a source of bugs both in our code and in the
JVM in every release of Cassandra.  Time to explore moving to blocking i/o, which is simpler,
more robust (in terms of the JVM implementation), and possibly more performant as well (http://paultyma.blogspot.com/2008/03/writing-java-multithreaded-servers.html).
