Alessandro Presta updated GIRAPH-224:
-------------------------------------
Attachment: GIRAPH-224-3.patch
Previous patch had a bug: I wasn't putting the combined messages back in
transientMessages.
The reason why the test seemed to work is because our unit tests use Hadoop RPC
by default, and I had no idea this was Netty-specific code.
> Server-side combiner

> Currently, if a VertexCombiner is defined in the Configuration, we use it on
> the client in order to optimize bandwidth and memory usage.
> On the server side, we can easily benefit in terms of memory by exploiting
> the combiner once more.
