Owen O'Malley created HIVE-4248: ----------------------------------- 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. -- This message is automatically generated by JIRA.
