Maybe @CJ-Wright or @jrmlhermitte has time here?

Sure, if I can get it to work I'll submit an example.

I don't have a ton of experience with async programming, but I can try look at an example.

Do you need something in a separate thread or can your entire application be asynchronous? Presumably if you are already using asyncio
then you should be somewhat comfortable with running asynchronous applications. You could consider moving to the Tornado event loop, which should also support asyncio applications.

I'm not sure. I'm listening to various websockets and they're all emitting events and awaiting each other. Everything works great except if I add a .timed_window()
to any stream then that stream locks up. I'm not sure what the problem is.

My code is in the github.com/snth/numismatic package.
In particular in https://github.com/snth/numismatic/blob/master/numismatic/exchanges.py on line 47 I would like to replace the .partition(...)
with .timed_window(interval=batch_size)
.

It looks like you already have an event loop running with asyncio. Here are the docs on using Asyncio event loops with tornado: http://www.tornadoweb.org/en/stable/asyncio.html
You can provide the timed_window
constructor with a loop=
keyword to give it the right event loop.
I agree with you that an example on how to use streamz with an asyncio application would be very valuable. If I get some time I'll write something up but unfortunately I can't guarantee that this will happen in the very near future. If you have the time I strongly encourage you to write up a small example and submit it. I think that others like yourself might also find it valuable.

Same but interested. I think it's a great opportunity start more discussion on this now. (Thanks for the ping @mrocklin )

I've created an example. Please see if it works for you too.

This was great. Closing
