Owen O'Malley created HIVE-3153: ----------------------------------- Summary: Release codecs and output streams between flushes of RCFile Key: HIVE-3153 URL: https://issues.apache.org/jira/browse/HIVE-3153 Project: Hive Issue Type: Improvement Components: Compression Reporter: Owen O'Malley Assignee: Owen O'Malley
Currently, RCFile writer holds a compression codec per a file and a compression output stream per a column. Especially for queries that use dynamic partitions this quickly consumes a lot of memory. I'd like flushRecords to get a codec from the pool and create the compression output stream in flushRecords. -- This message is automatically generated by JIRA.
