Thomas Jungblut commented on HAMA-367:
--------------------------------------
Good work! With snappy it seems to work for me.
However, we would like to have multiple compressors and a user defines this via
configuration.
So I guess we need a compressor/decompressor interface and the typical
reflection based class instantiation. But I think we just make a follow-up
issue for this.
Another thing would be testcases, you should include one ;)
Did you use the code formatter
(http://incubator.apache.org/hama/hama-eclipse-formatter.xml)? I think there
might be tabs instead of 3 spaces.

> As you know, the exchanging data between processes, is a core part of whole
> performance in Bulk Synchronous Parallel.
> In this research, we investigate BSP message data compression in the context
> of large-scale distributed message-passing systems to reduce the
> communication time of individual messages and to improve the bandwidth of the
> overall system.
