bounded-pool 0.0.2

Library for running tasks in bounded pool executors.

bounded_pool

Simplistic and universal bounded pool executor that allows to process N tasks as the same time while limiting size of the queue. Tasks can be functions or coroutines. Under the hood bounded_pool uses threads or processes, depending on used class. Refer to tests/test_basic.py for details.

Tasks will only be submited when there are available workers (specified by max_workers). You can specify max_queue_size to allow submiting more tasks than amount of available workers (so workers won't have to wait for task creation). Refer to tests/test_queue.py for details.

Exceptions inside of the tasks craeted with executors are ignored. Refer to tests/test_exceptions.py for details.

Example / Showcase

import time
from bounded_pool import BoundedThreadPoolExecutor


def test_example():
    futures = []

    with BoundedThreadPoolExecutor() as pool:
        for _ in range(64):
            future = pool.submit(time.sleep, 1)
            futures.append(future)

    assert futures

    for future in futures:
        assert future.done()
        assert future.result() is None
