aiothrottles¶

aiothrottles synchronization primitives are designed to be extension to asyncio synchronization primitives.

Usage¶

Throttle implements a rate limiting for asyncio task. A throttle can be used to guarantee limited access to a shared resources.

The preferred way to use a Throttle is an async with statement:

throttle = Throttle('3/s')

# ... later
async with throttle:
    # access shared state

which is equivalent to:

throttle  = Throttle('3/s')

# ... later
await throttle.acquire()
try:
    # access shared state
finally:
    throttle.release()

A call rate is determined by the rate argument. Pass the rate in the following formats:

rate examples:

pip install aiothrottles

or

python setup.py install

Python 3.6, 3.7, 3.8 and 3.9 are supported.
