[jira] [Commented] (GIRAPH-37) Implement Netty-backed IPC

    [ https://issues.apache.org/jira/browse/GIRAPH-37?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=13271696#comment-13271696 ] 

Avery Ching commented on GIRAPH-37:
-----------------------------------

@Claudio,

Vertex input superstep is a blocking operation when sending the vertices to the destination partition owners.  Now it's non-blocking, overlapping communication and computation.

Setup should be ignored.  That is the time to get all the map tasks and pick a master.

> GIRAPH-12 considered replacing the current Hadoop based rpc method with Netty, but didn't went in another direction. I think there is still value in this approach, and will also look at Finagle.
