----------------------------------------------------------------

When bucketing requirement is relaxed, CTAS can be successful.  How will acid write look like?
It cannot retain 1/ and 2/ subdirectories.  Should each leg rely on writerId to create a set
of unique tranche files across all subdirs so that acid "move" can put all of them into a
delta?  
Then how do we later remove the "move" for S3?

perhaps it should rely on statementId and create delta_x_x_0, delta_x_x_1, etc
