Subject [jira] [Created] (SPARK-15447) Performance test for ALS in Spark 2.0
Date Fri, 20 May 2016 16:49:12 GMT
Xiangrui Meng created SPARK-15447:
-------------------------------------

             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?
