System Design: How to Design a Rate Limiter?

What is a Rate Limiter?

Rate limiting refers to preventing the frequency of an operation from exceeding a defined limit. In large-scale systems, rate limiting is commonly used to protect underlying services and resources. In distributed systems, Rate limiting is used as a defensive mechanism to protect the availability of shared resources. It is also used to protect APIs from unintended or malicious overuse by limiting the number of requests that can reach our API in a given period of time.

In this blog, we’ll see how will tackle the question of designing a rate limiter in a system design interview.

Distributed Computing with Locks

Introduction

Having known of the prevalence of BigData in real-world scenarios, it’s time for us to understand how they work. This is a very important topic in understanding the principles behind system design and coordination among machines in big data. So let’s dive in.

Scenario:

Consider a scenario where there is a resource of data, and there is a worker machine that has to accomplish some task using that resource. For example, this worker is to process the data by accessing that resource. Remember that the data source is having huge data; that is, the data to be processed for the task is very huge.
