It sounds like you're looking to be able to find out when a job has finished working, no matter which node it was run on. No, River does not have a mechanism for that today. It's definitely something we've talked about though.

Thanks. Yeah, that's definitely a requirement of the queueing systems I'm working with.

It's effectively "run this remote function, and return when you have the result data".

Fan-out RPC (-ish) style stuff, rather than async "queue an email for sending later".
