Nick Pentreath updated SPARK-15447: ----------------------------------- Description: We made several changes to ALS in 2.0. It is necessary to run some tests to avoid performance regression. We should test (synthetic) datasets from 1 million ratings to 1 billion ratings. cc [~mlnick] [~holdenk] Do you have time to run some large-scale performance tests?
