Apurv Verma commented on HAMA-367:
----------------------------------
Please suggest what would be better as the next step
1) A compressor decompressor interface like in hadoop or
2) A simple factory class that does a reflection based instantiation of the
compression input/output stream classes which would be given in the
configuration.
So the user would need to put these properties in the conf files.
hama.bsp.message.compressioninputstream &
hama.bsp.message.compressionoutputstream
The values of these properties would be the fully classified name for the
compression input/output stream classes.

> 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.
