aiothrottles

aiothrottles synchronization primitives are designed to be extension (along the time) to asyncio synchronization primitives.

aiothrottles has the following basic synchronization primitives:

  • Throttle

For more details, see aiothrottles Documentation.

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:

  • "{integer limit}/{unit time}"
  • "{limit's numerator}/{limit's denominator}{unit time}"

Examples:

  • 4/s, 5/m, 6/h, 7/d
  • 1/second, 2/minute, 3/hour, 4/day
  • 1/3s, 12/37m, 1/5h, 8/3d
