Next Level gRPC With Kotlin and Coroutines

on YouTube ↗19m

" summary

Shows that 10,000 coroutines sleep for ~1s instead of 10,000s on threads and compares three toolchains: proto-plus channels, gRPC Kotlin official bindings and Square Wire. Demonstrates unary suspend functions replacing StreamObserver, bidi streams as Flow or request/response channels, and how suspension maps to backpressure. Proves cooperative cancellation propagates across network boundaries (client cancellation triggers server cancellation) and gives the pragmatic opt-out: wrap critical sections with context.nonCancelable.
