Distributed Rate Limiting Database Design

api-management rate-limiting concurrency distributed-systems
Prompt
Develop a PostgreSQL implementation of a distributed rate limiting system for API management. Create a high-performance sliding window rate limiting mechanism that can handle 50,000 concurrent API requests per second. Design a solution that prevents race conditions using row-level locking and supports dynamic rate limit configuration per API endpoint. Include mechanisms for atomic updates and precise tracking of request quotas across multiple database nodes.
