RabbitMQ broker implementation for PATIO

PATIO Rabbitmq

PATIO is an acronym for Python Asynchronous Task for AsyncIO.

This package provides RabbitMQ broker implementation.

Example

Task executor

import asyncio
import operator
from functools import reduce

from patio import Registry, ThreadPoolExecutor

from patio_rabbitmq import RabbitMQBroker


rpc = Registry(project="patio-rabbitmq", auto_naming=False)


@rpc("mul")
def mul(*args):
    return reduce(operator.mul, args)


async def main():
    async with ThreadPoolExecutor(rpc, max_workers=16) as executor:
        async with RabbitMQBroker(
            executor, amqp_url="amqp://guest:guest@localhost/",
        ) as broker:
            await broker.join()


if __name__ == "__main__":
    asyncio.run(main())

Task producer

import asyncio

from patio import NullExecutor, Registry

from patio_rabbitmq import RabbitMQBroker


async def main():
    async with NullExecutor(Registry(project="patio-rabbitmq")) as executor:
        async with RabbitMQBroker(
            executor, amqp_url="amqp://guest:guest@localhost/",
        ) as broker:
            print(
                await asyncio.gather(
                    *[
                        broker.call("mul", i, i, timeout=1) for i in range(10)
                    ]
                ),
            )


if __name__ == "__main__":
    asyncio.run(main())
