lately i am seeing a lot of this warning in graphx: org.apache.spark.graphx.impl.ShippableVertexPartitionOps: Joining two VertexPartitions with different indexes is slow.
i am using Graph.outerJoinVertices to join in data from a regular RDD (that is co-partitioned). i would like this operation to be fast, since i use it frequently. should i be doing something different?
