Sergey Shelukhin created HIVE-9331: -------------------------------------- Summary: get rid of pre-optimized-hashtable memory optimizations Key: HIVE-9331 URL: https://issues.apache.org/jira/browse/HIVE-9331 Project: Hive Issue Type: Bug Affects Versions: 0.15.0 Reporter: Sergey Shelukhin Assignee: Sergey Shelukhin
These were added in 13 because optimized hashtable couldn't make it in; they reduced memory usage by some amount (10-25%), and informed the design of the optimized hashtable, but now extra settings and code branches are just confusing and may have their own bugs. Might as well remove them. -- This message was sent by Atlassian JIRA (v6.3.4#6332)
