I explained the need for using B plus trees, how table data is stored in them, and how the tree is serialized and stored on disk. I also introduced a system design course I offer. I highlighted the limitations of naive data storage methods like linear scans and explained how B plus trees solve efficiency issues in insertions, updates, finds, deletes, and range queries by organizing data into nodes on disk. # Recommended videos and playlists If you liked this video, you will find the following videos and playlists helpful System Design: Designing Microservices: Database Engineering: Concurrency In-depth: Research paper dissections: Outage Dissections: Hash Table Internals: Bittorrent Internals: # Things you will find amusing Knowledge Base: Bookshelf: Papershelf: # Other socials I keep writing and sharing my practical experience and learnings every day, so if you resonate then follow along.
