Subject [jira] [Created] (SPARK-3671) Batch multiput updates within partitions
Date Wed, 24 Sep 2014 00:16:34 GMT
Ankur Dave created SPARK-3671:

             Summary: Batch multiput updates within partitions
                 Key: SPARK-3671
             Project: Spark
          Issue Type: Sub-task
          Components: Spark Core
            Reporter: Ankur Dave
            Assignee: Ankur Dave

Multiputs that touch the same 32-element leaf node multiple times will currently allocate
and throw away a 32-element array per updated element. Instead, we should batch together all
updates to the same leaf node and apply them in one step.
