Eugene Koifman created HIVE-19387: ------------------------------------- Summary: 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
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)
