Send messages in batches to reduce RPC overhead.
------------------------------------------------
Key: HAMA-380
URL: https://issues.apache.org/jira/browse/HAMA-380
Project: Hama
Issue Type: Improvement
Components: bsp
Affects Versions: 0.3.0
Reporter: Miklos Erdelyi
Fix For: 0.3.0
When profiling graph computations running on HAMA it turned out that huge
amount of time is spent in RPC calls.
To reduce this overhead I propose extending the GroomServer's API with a
put(BSPMessageBundle) method so that a group of messages can be transferred
from the caller to the callee at once. Also, the sync() operation should be
improved by sending messages in batches rather than one-by-one.
