Summary: Performance test for ALS in Spark 2.0
Key: SPARK-15447
URL: https://issues.apache.org/jira/browse/SPARK-15447
Project: Spark
Issue Type: Task
Components: ML
Affects Versions: 2.0.0
Reporter: Xiangrui Meng
Priority: Critical
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?
