RedisLimiter

• Description: Redis based rate limiter.

Pros:

• Redis is a relatively fast key-value storage.

• Stateless, the state is stored in a redis server that can be accessed across processes.

Cons:

• Although minimal, latency exists when the redis server is on another machine.

An extra installation is required: pip install pyot[redis]
