It's a bit less complex than our architecture since the response queue doesn't get deleted when the caller stops, but it can still go a long way. It was designed to support high-throughput workflows in big-data and computational science settings and is currently used by AiiDA for computational materials research around the world. on another console If the work you're doing on messages from queues is CPU-heavy and as long as number of cores in your CPU >= number of consumers, it is generally better to use this approach - unless your queues are empty most of the time and consumers won't utilize this Rabbitmq实现RPC通信.
