I think the issue is your unbounded stream: it never yields back to tokio and hence the tasks that receive the data will never be executed (even though they are scheduled), see <https://tokio.rs/blog/2020-04-preemption> and <https://docs.rs/tokio/latest/tokio/task/fn.yield_now.html>. I'm pretty sure the repartition channels are correct. I've added a bunch of printlns and they wake the receivers but the receiver never is executed by tokio. -- This is an automated message from the Apache Git Service.
