Subject [jira] [Commented] (HAMA-644) Messaging Scalability Improvement
Date Wed, 17 Oct 2012 17:12:03 GMT

    [ https://issues.apache.org/jira/browse/HAMA-644?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=13478043#comment-13478043

Suraj Menon commented on HAMA-644:
----------------------------------

Updating and replying to the following comment from Apurv:
"Basically I wanted to replace queue with buffer implementation which is
segmented so as to offer more parallelism. I am okay with Suraj's design
also. We'll see which gives better performance and that too if I ever
finish it. :P

In either case, we are going to use ByteBuffer and I propose we have a reusable byte array
service that provides you a ByteBuffer wrapping a range from that byte array. Otherwise for
every superstep we would be building and tearing down ByteBuffer objects.
