Comment 11 for bug 1661510

I have a brief example of how to use TransportOptions in the project update for last cycle: https://docs.google.com/presentation/d/1nFN2qWQJF7sUmUBDnEU66MDl7z5d6aO2AmE8l2zmPJ0/edit#slide=id.g6221d147b8_1_10 (it's slide 5 if the link doesn't take you directly there).

I also have a bug open to document this better since there's really nothing in the published docs right now: https://bugs.launchpad.net/oslo.messaging/+bug/1849741

And if you want to listen to me ramble about this it's in the project update video: https://youtu.be/gNwWgedIDxc?t=238
