A modern programming language that makes developers happier.

Hi everyone! I'm looking to implement a long-living server stream with gRPC that clients can subscribe to.

Context: there is a group of users with users and a lead user, when the lead starts and action `performAction()` which is a unary RPC. I want to notify the other users with information about that action. I would expect those members to be subscribed to another long-living RPC that facilitates sending that information.

Do you have any examples of how can achieve that in Kotlin? I was looking into something like:
<https://dev.bitolog.com/grpc-long-lived-streaming/>
<https://sultanov.dev/blog/grpc-long-lived-streaming-using-observer-pattern/>

But those implementations are written in Go and Java, and I'm struggling to find examples in Kotlin

Just implement grpc. Not need todo anything special to make it long lived. Just use a grpc channel. Should work
