WorkerIO

WorkerIO

A tool that allows you to create your own workers and distribute work among them.

Each worker creates its own thread in which it will fetch jobs from the queue.SimpleQueue queue and execute them in its execute method. The result of the job is returned using asyncio.Future.

[!WARNING] Since everything will be executed in another thread, use thread-safe functions. Do not modify files unless you are sure they are not open in another worker.

Basic examples

class MyUrlWorker(workerio.Worker):
    def execute(self, url: str):
        return get(url).text


manager = workerio.Manager()
manager.add_worker(MyUrlWorker())

async def main(): 
    manager.start_all()

    result = await manager.put_work(MyUrlWorker, "https://example.com")
    print(result)

    manager.stop_all_nowait()

if __name__ == "__main__":
