System Design Interview: Decentralized Web Crawler
The article discusses the design of a decentralized web crawler that operates without a central component. Each node in the system runs independently and must agree on crawling tasks without coordination. The design emphasizes scalability, fault tolerance, and eventual coverage of web pages while avoiding duplicates.
- ▪A decentralized web crawler operates across independent nodes without shared infrastructure.
- ▪Each node is responsible for crawling URLs based on a hashed key that determines ownership.
- ▪The system is designed to handle billions of URLs and thousands of nodes while remaining fault-tolerant.
