Aihua Xu created HIVE-13616: ------------------------------- Summary: Investigate renaming a table without invalidating the column stats Key: HIVE-13616 URL: https://issues.apache.org/jira/browse/HIVE-13616 Project: Hive Issue Type: Improvement Components: Metastore Reporter: Aihua Xu Assignee: Aihua Xu
Right now when we rename a table, we clear the column stats rather than updating it (HIVE-9720) since ObjectStore uses DN to talk to DB. Investigate the possibility that if we can achieve updating the stats without rescanning the whole table. -- This message was sent by Atlassian JIRA (v6.3.4#6332)
