    Description

      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?
