Paddles: A Minimal Ping-Pong Example

This crate demonstrates a minimal ping-pong interaction using the Flawless framework for durable execution and memory passing over HTTP. It features two actors, Pinger and Ponger, that send a "ball" back and forth via HTTP requests until the number of rallies is reached.

Features

  • Durable Execution: Uses Flawless workflows for reliable, long-running tasks.
  • Memory Passing Over HTTP: Communication between actors via HTTP post requests.
  • Idempotent Actions: Ensures durable message handling in case of failure.

Quick Start

  1. Clone the repository and navigate to the project directory.
  2. Ensure Flawless CLI is installed and running: 
    flawless up
  3. Run the example: 
    cargo run

The Pinger and Ponger actors will start, and they will ping-pong a ball back and forth with a 1 second delay over HTTP until the rally count is reached.

Durability Test

  1. Kill the flawless server while the rally is going.
  2. Start it back up again and observe the power of durable execution: 
    flawless up

Requirements

  • Rust
  • Flawless CLI for execution orchestration
