---------------------------------------
Yeah, I didn't notice alberto had also created a ticket, we can mark one as
duplicate.
The thing is, I definitely would expect the stream to fail if I typo the name
of the topic. I'm not 100% certain without trying it out whether you can tell
the difference between a topic that doesn't exist and a topic that doesn't have
messages, solely through the metadata api.

> have messages yet.
> Should either try to work around this, or document that topics need messages
> before starting the stream.
