Pregel messages serialized in local machine?
This is a question on using the Pregel function in GraphX. Does a message get serialized and then de-serialized in the scenario where both the source and the destination vertices are in the same compute node/machine?

Yes, message passing currently uses partitionBy, which shuffles all messages, including ones to the same machine, by serializing them and writing them to disk.
