Re: Calcite Streaming and Mongo

That would be great and an awesome example of an adapter using streaming. I
haven't looked closely at Mongo's change streams, but you'd have to see if
the semantics of the stream are suitable for exposing existing tables also
as streams or if it would make more sense to separate streams and tables.
