Why is rate limiting used?
- Avoid resource starvation due to a Denial of Service (DoS) attack.
- Ensure that servers are not overburdened. Using rate restriction per user
- ensures fair and reasonable use without harming other users.
- Control the flow of information, for example, prevent a single worker from
- accumulating a backlog of unprocessed items while other workers are idle.
How to Design a Rate Limiter API | Learn System Design
A Rate Limiter API is a tool that developers can use to define rules that specify how many requests can be made in a given time period and what actions should be taken when these limits are exceeded.
Rate limiting is an essential technique used in software systems to control the rate of incoming requests. It helps to prevent the overloading of servers by limiting the number of requests that can be made in a given time frame.
It helps to prevent a high volume of requests from overwhelming a server or API. Here is a basic design for a rate limiter API In this article, we will discuss the design of a rate limiter API, including its requirements, high-level design, and algorithms used for rate limiting.
