+1 for longs as IDs.
Not so much in favour of Strings for the user ID because the row index
could also denote the actual item ID if you swap the indices. Furthermore,
you can always add a transformer which assigns unique IDs to names.

+1 for using long for both IDs.
But I don't understand what's the advantage of using a String as user ID.

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 wante
+1 for generalisation.
@Ronny: Could you create a JIRA issue related to this?

Hi Ronny,
I agree with you and I would go even further and generalize it overall. So
that the movieID could be of type Long or Int and the userID of type String.
This would increase usability of the ALS implementation :)
