Rate limiter for async functions using Redis as a backend

asyncio-redis-rate-limit

Rate limiter for async functions using Redis as a backend.

Features

• Small and simple
• Can be used as a decorator or as a context manager
• Can be used for both clients and servers
• Works with asyncio
• Works with any amount of processes
• Works with both redis.asyncio.client.Redis and aioredis
• Free of race-conditions (hopefully!)
• Supports redis since 7.0
• Fully typed with annotations and checked with mypy, PEP561 compatible

Installation

pip install asyncio-redis-rate-limit

Extras available:

• pip install asyncio-redis-rate-limit[redis]
• pip install asyncio-redis-rate-limit[aioredis] (for python versions <3.11)

Example

As a decorator:

>>> from asyncio_redis_rate_limit import rate_limit, RateSpec
>>> from redis.asyncio import Redis as AsyncRedis  # pip install redis

>>> redis = AsyncRedis.from_url('redis://localhost:6379')

>>> @rate_limit(
...    rate_spec=RateSpec(requests=1200, seconds=60),
...    backend=redis,
... )
... async def request() -> ...:
...     ...   # Do something useful! Call this function as usual.

Or as a context manager:

>>> from asyncio_redis_rate_limit import RateLimiter, RateSpec
>>> from redis.asyncio import Redis as AsyncRedis  # pip install redis

>>> redis = AsyncRedis.from_url('redis://localhost:6379')

>>> async def request() -> ...:
...     async with RateLimiter(
...         unique_key='api-name.com',
...         backend=redis,
...         rate_spec=RateSpec(requests=5, seconds=1),
...     ):
...         ...  # Do the request itself.
