    To test ADF copy data performance, we moved less than 100GB from one ASDW to another, both running at DWU1000c. Export to blob step took 1hr 4 minutes. Import from blob to ASDW took 4 minutes. Polybase at both ends would have improved performance by up to 90%.

    Also there are data science/ml scenarios where I may want to copy filtered subsets of warehouse data out to blob to further manipulate and ingest with other tools that are too chatty or client based that I do not want connecting directly to the warehouse.

    Especially now that Hyperscale is going to be available, this would be a very useful feature. Hyperscale would make a superior data mart platform, but only if it could be loaded quickly enough.
