Strategies#
Synchronous Strategies#
The available built in rate limiting strategies which expect
a single parameter: a subclass of Storage.
Provided by limits.strategies
- class FixedWindowRateLimiter(storage: Storage | limits.aio.storage.Storage)[source]#
Reference: Fixed Window
- test(item: RateLimitItem, *identifiers: str) bool[source]#
Check if the rate limit can be consumed
- get_window_stats(item: RateLimitItem, *identifiers: str) WindowStats[source]#
Query the reset time and remaining amount for the limit
- class FixedWindowElasticExpiryRateLimiter(storage: Storage | limits.aio.storage.Storage)[source]#
Reference: Fixed Window with Elastic Expiry
- get_window_stats(item: RateLimitItem, *identifiers: str) WindowStats#
Query the reset time and remaining amount for the limit
- class MovingWindowRateLimiter(storage: Storage | limits.aio.storage.Storage)[source]#
Reference: Moving Window

Check if the rate limit can be consumed
- get_window_stats(item: RateLimitItem, *identifiers: str) WindowStats[source]#
returns the number of requests remaining within this limit.
All strategies implement the same abstract base class:

- abstract hit(item: RateLimitItem, *identifiers: str, cost: int = 1) bool[source]#
Consume the rate limit

Check the rate limit without consuming from it.
- abstract get_window_stats(item: RateLimitItem, *identifiers: str) WindowStats[source]#
Query the reset time and remaining amount for the limit

expose async variants and expect a subclass of limits.aio.storage.Storage

Storage#
Storage Factory function#
Provided by limits.storage
- storage_from_string(storage_string: str, **options: float | str | bool) Storage | Storage[source]#
Factory function to get an instance of the storage class based on the uri of the storage. In most cases using it should be sufficient instead of directly instantiating the storage classes. for example:
from limits.storage import storage_from_string memory = from_string("memory://") memcached = from_string("memcached://localhost:11211") redis = from_string("redis://localhost:6379")
The same function can be used to construct the Async Storage variants, for example:
from limits.storage import storage_from_string memory = storage_from_string("async+memory://") memcached = storage_from_string("async+memcached://localhost:11211") redis = storage_from_string("async+redis://localhost:6379")
- Parameters:
storage_string¶ – a string of the form
scheme://host:port. More details about supported storage schemes can be found at Storage schemeoptions¶ – all remaining keyword arguments are passed to the constructor matched by
storage_string.
- Raises:
ConfigurationError – when the
storage_stringcannot be mapped to a registeredlimits.storage.Storageorlimits.aio.storage.Storageinstance.

Depends on redis.
- Parameters:
uri¶ – uri of the form
redis://[:password]@host:port,redis://[:password]@host:port/db,rediss://[:password]@host:port,redis+unix:///path/to/socketc. This uri is passed directly toredis.from_url()except for the case ofredis+unix://where it is replaced withunix://.connection_pool¶ – if provided, the redis client is initialized with the connection pool and any other params passed as
optionswrap_exceptions¶ – Whether to wrap storage exceptions in
limits.errors.StorageErrorbefore raising it.options¶ – all remaining keyword arguments are passed directly to the constructor of

- Raises:
ConfigurationError – when the redis library is not available
- DEPENDENCIES: Dict[str, Version | None] | List[str] = {'redis': <Version('3.0')>}#
The python modules this class has a dependency on. Used to lazily populate the
dependencies
- incr(key: str, expiry: int, elastic_expiry: bool = False, amount: int = 1) int[source]#
increments the counter for a given rate limit key
Redis Cluster Storage#
- class RedisClusterStorage(*args: Any, **kwargs: Any)[source]#
Rate limit storage with redis cluster as backend
Depends on redis.
Changed in version 2.5.0: Cluster support was provided by the redis-py-cluster library which has been absorbed into the official redis client. By default the
redis.cluster.RedisClusterclient will be used however if the version of the package is lower than4.2.0the implementation will fallback to trying to userediscluster.RedisCluster.- Parameters:
uri¶ – url of the form
redis+cluster://[:password]@host:port,host:portoptions¶ – all remaining keyword arguments are passed directly to the constructor of
redis.cluster.RedisCluster
- Raises:
ConfigurationError – when the redis library is not available or if the redis cluster cannot be reached.
- DEFAULT_OPTIONS: Dict[str, float | str | bool] = {'max_connections': 1000}#
Default options passed to the
RedisCluster
- DEPENDENCIES: Dict[str, Version | None] | List[str] = {'redis': <Version('4.2.0')>, 'rediscluster': <Version('2.0.0')>}#

Redis Clusters are sharded and deleting across shards can’t be done atomically. Because of this, this reset loops over all keys that are prefixed with
self.PREFIXand calls delete on them, one at a time.Warning
