-----------------------------------
Summary: Implement a memory manager for ORC
Key: HIVE-4248
URL: https://issues.apache.org/jira/browse/HIVE-4248
Project: Hive
Issue Type: New Feature
Components: Serializers/Deserializers
Reporter: Owen O'Malley
Assignee: Owen O'Malley
With the large default stripe size (256MB) and dynamic partitions, it is quite
easy for users to run out of memory when writing ORC files. We probably need a
solution that keeps track of the total number of concurrent ORC writers and
divides the available heap space between them.
