> 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?
