sysdesign-rate-limiting-strategies

What problem does it solve?

Rate-limiting strategy selection and implementation guidance to prevent abuse while preserving user experience.

Core Features & Use Cases

• Pick among token bucket, leaky bucket, fixed window, and sliding window based on burst patterns.
• Decide between stateful and stateless counters and appropriate counter stores (Redis, DynamoDB, in-process).
• Define a clear 429 contract, shadow-mode rollout, and observability dashboards for per-scope blocking.

Quick Start

Provide a design outline that selects one rate-limiting algorithm (token bucket, leaky bucket, fixed window, or sliding window), chooses a stateful or stateless counter store, and documents the burst handling and 429 contract.
