Liyin Tang resolved HIVE-1702. ------------------------------ Resolution: Won't Fix Release Note: JDBM will be removed from Hive > optimize JDBM to make mapjoin faster > ------------------------------------ > > Key: HIVE-1702 > URL: https://issues.apache.org/jira/browse/HIVE-1702 > Project: Hive > Issue Type: Improvement > Components: Query Processor > Reporter: Namit Jain > Assignee: Liyin Tang > > Htree.get() cost 70% total time. It could help a lot if there is bloom filter > here to avoid unneeded get() if we know for sure the given key is not in > JDBM. (we can generate the bloom filter when doing the jdbm sink, and read > into memory when doing read. ) > Copied from https://issues.apache.org/jira/browse/HIVE-1700 -- This message is automatically generated by JIRA. - You can reply to this email to add a comment to the issue online.
