--------------------------------------------
Summary: PageRank: make the use of one-to-many messaging
configurable
Key: GIRAPH-1189
URL: https://issues.apache.org/jira/browse/GIRAPH-1189
Project: Giraph
Issue Type: Improvement
Reporter: Dionysios Logothetis
The PageRank implementation uses one-to-many messaging to reduce the amount of
traffic sent. The corresponding message request
(SendWorkerOneMessageToManyRequest) creates ByteArrayVertexIdMessages
instances before adding the messages to the Message Store. When the number of
messages is big, the creation of this instances can fail.
Adding an option here to enable/disable the use of one-to-many messaging.
