Rust async microservices: rate limiting, backpressure, batching and middleware

Rust Async Microservices, Tamed: Rate Limiting, Backpressure, Batching, and Middleware

Bold claim up front: stability is not “slow.” Stability is making “fast” happen in an orderly way. With the gates placed at the right spots, even a flood can be channeled into rivers. Think about a subway during Monday rush hour. Entry turnstiles regulate inflow, platforms enforce headcount, trains add extra cars, and the PA system orchestrates everything. That is exactly what microservices must do under high concurrency. Your Rust service needs the same four gates: rate limiting, backpressure, batching, and a smart brain of middleware. ...
