I have a Phoenix application that relies heavily on channels.
What we’re observing is that when we call the App.Endpoint.broadcast function, about half of the time nothing is coming over the wire.
I can sit there and repeatedly call the broadcast function and never receive 100% success on broadcast.
I will say that when a user joins a channel they can be subscribed to at least 100 topics. Don’t know if that’s a factor.
Does anyone have any tips on how to debug this situation?
