I delved into the basics of database structure, disk block reading, and the role of indexes. Without indexes, reading all rows sequentially can be slow, but with indexes, queries become much faster. I demonstrated how creating an index on a specific column can significantly enhance query performance. By efficiently utilizing indexes, database operations can achieve up to an 8x improvement in speed, showcasing the crucial role of indexes in optimizing database performance. • Recommended videos and playlists • If you liked this video, you will find the following videos and playlists helpful • System Design: • PostgreSQL connection management and ... • Designing Microservices: • Advantages of adopting a microservice... • Database Engineering: • How nested loop, hash, and merge join... • Concurrency In-depth: • How to write efficient and fair multi... • Research paper dissections: • The Google File System - Paper Explained • Outage Dissections: • Dissecting GitHub Outage and things t... • Hash Table Internals: • Internal Structure of a Hash Table • Bittorrent Internals: • Introduction to BitTorrent and the pr... • Things you will find amusing • Knowledge Base: https://arpitbhayani.me/knowledge-base • Bookshelf: https://arpitbhayani.me/bookshelf • Papershelf: https://arpitbhayani.me/papershelf • Other socials • I keep writing and sharing my practical experience and learnings every day, so if you resonate then follow along.
