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?
