As I commented in my previous message, asyncio.Queue is not
thread-safe, so it's very important that the put calls here be done on
the event loop thread using event_loop.call_soon_threadsafe. This
could be the cause of the strange behavior you're seeing in getting
the results.
Using call_soon_threadsafe makes all the difference. The rows are now
retrieved instantly.
I have read the other messages, and I can see that there are some clever
ideas there. However, having found something that seems to work and that I
feel comfortable with, I plan to run with this for the time being.
Thanks to all for the very stimulating discussion.
Frank
