We are switching to the new Discovery service from the Retrieve and Rank service on Bluemix. This requires quite a bit of code rewrite and I'm getting a strange error message while transferring our answer units to Discovery:
Error: The service is busy processing 20 of your documents. Please wait for some of the documents to complete, then try again.
Is there some kind of rate limit on inserting documents into Discovery? If so, how do we increase or better, eliminate it?
