Summary

In this chapter, we have explored the system design of a Twitter-like service, covering functional and non-functional requirements, data modeling, scalability considerations, and architectural components. We examined both high-level and low-level designs, focusing on key services such as Tweet Service, User Service, Timeline Service, and Search Service. The system architecture leverages horizontal scaling, data partitioning, and distributed processing to handle a large number of users and interactions efficiently.

Throughout our discussion, we emphasized scalability, reliability, and performance, incorporating techniques such as caching and asynchronous processing to improve response times and handle high throughput. As we conclude, it’s important to note that designing such a service is an ongoing process, requiring flexibility and adaptability to evolving user needs and technological advancements. By following the principles and best practices outlined here, developers...
