Building a Social Media Feed
Design a scalable social media feed system, addressing challenges like fan-out, content delivery, and real-time updates.
Intro to Social Media Feeds
A social media feed is a core feature that displays a stream of content to users. It's how platforms like Twitter, Facebook, or Instagram keep you engaged.
Feeds need to be fast, reliable, and capable of handling massive amounts of data and users. This lesson explores how to design such a system.
Key Feed System Components
To build a feed, we need to understand its fundamental entities:
- Users: Individuals who create posts and follow others.
- Posts: The actual content (text, images, videos) created by users.
- Followers: Users who subscribe to receive updates from other users.
The challenge is efficiently delivering posts from followed users to their followers' feeds.
