Re: External table novelties

Daniel Fink



Very creative idea, IMHO. Here's one thought...An application loads
and/or processes data. To track the progress, you could do queries
against actual tables, or you could have the app write 'milestones' to
the pipe, then you query that 'table'. If you aren't querying the pipe,
will the output in the pipe be 'saved' in the pipe until you read it?
