> Message communication overhead between master aggregation and vertex
> computation supersteps
> -------------------------------------------------------------------------------------------

> Key: HAMA-843
> URL: https://issues.apache.org/jira/browse/HAMA-843
> Project: Hama
> Issue Type: Improvement
> Components: graph
> Affects Versions: 0.6.3
> Reporter: Edward J. Yoon
> Assignee: Edward J. Yoon
> Fix For: 0.7.0

>
> Within doAggregationUpdates() method, we sends unconsumed messages to next
> superstep using send() method. This is huge overhead.
> {code}
> // in case we need to sync, we need to replay the messages that already
> // are added to the queue. This prevents loosing messages when using
> // aggregators.
> if (firstVertexMessage != null) {
> peer.send(peer.getPeerName(), firstVertexMessage);
> }
> GraphJobMessage msg = null;
> while ((msg = peer.getCurrentMessage()) != null) {
> peer.send(peer.getPeerName(), msg);
> }
> {code}
> Once HAMA-842 is done, we can get rid of this overhead.
