Thomas Jungblut commented on HAMA-358:
--------------------------------------

Here is avro:

https://github.com/thomasjungblut/hama-avro/blob/master/src/de/jungblut/avro/AvroMessageServiceImpl.java

I think the overhead might be larger than the RPC of Hadoop, but it's just a 
guess.

> The goal of this project is performance evaluation of RPC frameworks (e.g., 
> Hadoop RPC, Thrift, Google Protobuf, ..., etc) to figure out which is the 
> best solution for Hama BSP communication. Currently Hama is using Hadoop RPC 
> to communicate and transfer messages between BSP workers.
