Inngest Flow Control

This covers all of Inngest's flow control primitives with a decision tree that actually helps. You get concurrency limits (including multi-tenant keying), throttling, rate limiting, debounce, priority queues, singleton modes, and event batching. The examples are practical: handling OpenAI rate limits with account-level concurrency, debouncing document saves after users stop typing, prioritizing VIP orders ahead in the queue. The quick decision guide at the top is genuinely useful for picking the right primitive. One thing to note is the TypeScript focus, though the concepts translate to Python and Go. If you're building event-driven systems that need backpressure or fairness guarantees, this is comprehensive.
