Subject [jira] Commented: (CAMEL-2496) StreamCache/Splitter race condition
Date Mon, 01 Mar 2010 16:05:44 GMT

    [ https://issues.apache.org/activemq/browse/CAMEL-2496?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=57936#action_57936

Claus Ibsen commented on CAMEL-2496:
------------------------------------

I think we should use the new HawtDB as file based stream cache in the future. 

It got all the bells and whistles to be fast and leverages NIO and memory mapped IO and whatnot.
But that can be done when we overhaul stream caching in 2.x, once we get the time for that
:)

> I believe it must be a race condition when several threads are passing through the splitter,
in the above case I'm using a seda queue with 5 threads.  Am logging this now as I'm not sure
what time I'll have to investigate further this week.
