in-memory optimization

2017-04-24 Thread Robert Schwarzenberg
Hello, I have a question regarding the loop-awareness of Flink wrt invariant datasets. Does Flink serialize the DataSet 'points' in line 85 https://github.com/apache/flink/blob/master/flink-examples/flink-examples-batch/src/main/scala/org/apache/flink/examples/scala/clustering/KMeans.scala

hash preservation

that the hash values are indeed preserved during MapReduce. However, hacking the library is a very clumsy approach. My question now is: does Flink provide a more elegant solution? Thanks for your help! Regards, Robert Schwarzenberg
