[jira] [Comment Edited] (SPARK-6028) Provide an alternative RPC implementation based on the network transport module

["Colin Scott (JIRA)" <ji...@apache.org>]

    [ https://issues.apache.org/jira/browse/SPARK-6028?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=14637443#comment-14637443 ]

-------------------------------------------------------------

Curious: does this new RPC implementation use TCP as its underlying transport protocol, or UDP? In other words, does the underlying transport protocol guarantee in-order delivery between hosts?
(I believe akka-remote uses TCP by default.)

Thanks!

> Network transport module implements a low level RPC interface. We can build a new RPC implementation on top of that to replace Akka's.
