Hi guys. Need some help with coroutines. I want to achieve something: From one (or many coroutines / threads) something is marked as dirty. Another coroutine waits for that marker and starts a (long running) calculation. I want to have two things: - the calculation should only run at most once per second - I do not care how often the dirty marker is set (probably very often). I just want to calculate once.

Do you want to run it once per second, or only once ever? The two points seems to contradict each other 🙂

At most once per second. But only if the dirty marker is set

Right. Maybe some combination of a conflated channel and a ticker channel will work?

"Conflated channel" might be the thing I am looking for. Thanks for that hint. Will read it up
