Azure SQL data warehouse - do transaction limits apply to CTAS opperations? Azure SQL Data Warehouse has limits on the maximum size of a transaction (as documented here). As CTAS operations cannot be performed inside a transaction, I was wondering if these limits still applied?

The transaction safety limits only apply to fully logged operations. CTAS is capable of being minimally logged.  So answer depends, if CTAS is minimally logged safety limit does not apply and vice versa.


  Unlike fully logged operations, which use the transaction log to keep
  track of every row change, minimally logged operations keep track of
  extent allocations and meta-data changes only. Therefore, minimal
  logging involves logging only the information that is required to
  rollback the transaction in the event of a failure or an explicit
  request (ROLLBACK TRAN). As much less information is tracked in the
  transaction log, a minimally logged operation performs better than a
  similarly sized fully logged operation. Furthermore, because fewer
  writes go the transaction log, a much smaller amount of log data is
  generated and so is more I/O efficient.
