CORE DEFINITION

Limit the number of requests a user or service can initiate within a unit of time. Requests exceeding the quota are rejected.

SCAFFOLDING EFFECT

psychology

Reduce cognitive load

Protect the system from being overwhelmed. Learn to say "no" at work. Set your bandwidth limit (e.g., only handle 3 urgent tasks per day). Beyond that, you must reject or queue, otherwise you will crash (downtime), which benefits no one.

anchor

Anchor fast decisions

Throttling constrains resource consumption by setting a rate limit (e.g., N requests per second, token bucket/leaky bucket algorithm). Requests exceeding the quota are rejected or queued. The mechanism is to "protect limited bandwidth"—using explicit rejection to avoid system avalanche (cascading failure) due to overload, replacing "unlimited acceptance" with "bounded and controllable".
