Change graph mutation RPC API to a kind of message
--------------------------------------------------
Key: GIRAPH-41
URL: https://issues.apache.org/jira/browse/GIRAPH-41
Project: Giraph
Issue Type: Improvement
Components: bsp
Reporter: Hyunsik Choi
Graph mutation functions (e.g., addVertexRequest, addEdgeRequest..) directly
invoke RPC functions.
In processing, these RPC calls may incur delays caused by TCP round-trip time
and communication overheads caused by frequent RPC call. Especially, when many
workers try to mutate vertices and edges simultaneously, the synchronization
overheads may also occur in receiving sides. It may become intensive as the
size of cluster increases.
If we change graph mutation API to a kind of messages, it would be more
efficient. If possible, graph mutation message API and data messages API (i.e.,
sendMsg)can be integrated into one message passing API.
What do you think about that?
