Subject in-memory optimization
Date Mon, 24 Apr 2017 14:20:02 GMT
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



each iteration or are there in-memory optimization procedures in place?

Thanks for your help!

Regards,
Robert
