This blog post discusses the challenges of rate limiting in shared API quotas, highlighting how a traditional fixed limit fails when multiple clients consume the quota variably. It introduces Nall.RateLimiting.Adaptive, a .NET library that adjusts the rate limits of HttpClients based on API responses (429 errors and Retry-After headers) for effective quota management. The author shares a real-world scenario using a demo app to illustrate how adaptive rate limiting solves the noisy neighbor problem in a distributed system.
