[jira] [Created] (GIRAPH-753) Efficient dense matrix aggregators

Herald Kllapi created GIRAPH-753:
------------------------------------

             Summary: Efficient dense matrix aggregators
                 Key: GIRAPH-753
                 URL: https://issues.apache.org/jira/browse/GIRAPH-753
             Project: Giraph
          Issue Type: New Feature
            Reporter: Herald Kllapi


In applications where a matrix is needed, is not efficient to have an aggregator per entry. This update provides the same functionality with an aggregator per matrix row. This implementation uses an array per row and is efficient when the matrices are dense.
