---------------------------------
Summary: Batch multiput updates within partitions
Key: SPARK-3671
URL: https://issues.apache.org/jira/browse/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.
