Eugene Koifman updated HIVE-19387: ---------------------------------- Target Version/s: 3.1.0 (was: 3.0.0) > CLONE - Truncate table for Acid tables > -------------------------------------- > > Key: HIVE-19387 > URL: https://issues.apache.org/jira/browse/HIVE-19387 > Project: Hive > Issue Type: New Feature > Components: Transactions > Reporter: Eugene Koifman > Assignee: Eugene Koifman > Priority: Major > > How should this work? Should it work like Insert Overwrite T select * from T > where 1=2? > This should create a new empty base_x/ and thus operate w/o violating > Snapshot Isolation semantics. > This makes sense for specific partition or unpartitioned table. What about > "Truncate T" where T is partitioned? Is the expectation to wipe out all > partition info or to make each partition empty? -- This message was sent by Atlassian JIRA (v7.6.3#76005)
