To improve performance we have introduced a new version of -[`mapReduceTriplets`][Graph.mapReduceTriplets] called -[`aggregateMessages`][Graph.aggregateMessages] which takes the messages previously returned from -[`mapReduceTriplets`][Graph.mapReduceTriplets] through a callback ([`EdgeContext`][EdgeContext]) -rather than by return value. -We are deprecating [`mapReduceTriplets`][Graph.mapReduceTriplets] and encourage users to consult -the [transition guide](#mrTripletsTransition). - -2. In Spark 1.0 and 1.1, the type signature of [`EdgeRDD`][EdgeRDD] switched from -`EdgeRDD[ED]` to `EdgeRDD[ED, VD]` to enable some caching optimizations. We have since discovered -a more elegant solution and have restored the type signature to the more natural `EdgeRDD[ED]` type. - # Getting Started To get started you first need to import Spark and GraphX into your project, as follows: |
