Subject Re: Apache Flink 0.9 ALS API
Date Sat, 13 Jun 2015 12:07:41 GMT
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 :)

Best regards,
Felix
