AI Dev Tool: Async Token-Bucket Rate Limiter & Circuit Breaker (Python 3.12)
This module implements an asynchronous token-bucket rate limiter and circuit breaker.
It provides bounded concurrency and exponential backoff with jitter for handling
rate limiting and circuit breaking. The module uses structured JSON logging and
deterministic error handling.
The token-bucket rate limiter is designed to limit the rate at which requests are
sent to a service. It uses a bucket to store tokens, which are added to the bucket
at a specified rate. When a request is made, a token is removed from the bucket.
If the bucket is empty, the request is blocked until a token is added.
The circuit breaker is designed to detect when a service is not responding and
prevent further requests from being sent to it. It uses a counter to track the
number of consecutive failures. If the counter exceeds a specified threshold,
the circuit breaker is tripped and requests are blocked for a specified period.
To use this module, run the following command:
python -m ai_dev_tool --rate 10 --burst 5 --threshold 3 --timeout 30
This will run the module with a rate of 10 requests per second, a burst size⚡ Instant browser download upon Stripe redirect • 🛡️ Permissive MIT Commercial License
