grpc-python-best-practices

Python gRPC async-first Kubernetes-native best practices using grpc.aio — server bootstrap with graceful shutdown that flips Health to NOT_SERVING before server.stop(), shared per-process channel factory, canonical decorator pattern (@grpc_logger + @grpc_error_handler) for cross-cutting concerns, max_connection_age_* triad for HPA rebalancing, client-side LB via dns:/// + round_robin + service config JSON over a Kubernetes headless Service (no service mesh), ERROR_MAP + google.rpc.Status rich error model, client-side translation hierarchy
