AppNet RPC (aRPC)

AppNet RPC (arpc) is a minimal, fast, and pluggable Remote Procedure Call framework built on top of UDP, with support for customizable serialization formats.

Prerequisites

• Go 1.20 or later
  • For installation instructions, see Go’s Getting Started guide.

Quick Start

See examples/README.md

Note: If you're running aRPC on Kubernetes and want to connect using a DNS name (e.g., server.default.svc.cluster.local), you must:

1. Define your service as a headless service by setting:

   spec:
     clusterIP: None

2. Explicitly specify the UDP protocol for your service port:

   ports:
     - port: 9000
       targetPort: 9000
       protocol: UDP

3. Use the fully qualified domain name (FQDN) when specifying the server address, such as server.default.svc.cluster.local:9000.

Without these settings, Kubernetes will assign a default TCP-based ClusterIP, which does not work properly for aRPC(UDP) communication.
