    Can you please give us an update on full fidelity? Is this feature in preview yet?

      @David I am already experimenting with full fidelity schema on SQL API and it is in place. Only works on newly created accounts or accounts with no analytics enabled before.

        Did you register for private preview? How can you experiment with it if it hasn’t been released to public preview yet?
