Apache Flink 0.9 ALS API

[Ronny Bräunlich]

Hello everybody,

for a university project we use the current implementation of ALS in Flink 0.9 
and we were wondering about the API of predict() and fit() requiring a 
DataSet[(Int, Int)] or DataSet[(Int, Int, Double]) respectively, because the 
range of Int is quite limited.
That is why we wanted to ask you if it wouldn’t be advantageous to change Int 
to Long, to allow more values.
Please let me know what you think about it.

Cheers,
Ronny
