> 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?
