How do indexes make databases read faster?

About

I am a software engineer passionate about System Architecture, Language Internals, Distributed databases, and Advanced Algorithms. I am on a mission to bring out the best engineering stories from around the world. If you are doing something interesting and want me to dissect and talk about it, drop me an email at [email protected]. Before co-founding Profile.fyi, I was a Staff Engineer at Google leading the Dataproc India team in providing a managed big data ecosystem to GCP customers. I hold 10+ years of experience in building and scaling backend services across domains and companies like Unacademy, Amazon, Practo, and D. E. Shaw. I keep diving deep into engineering details and share my learnings by across my socials and videos on YouTube. To put my learning to practice, I keep building things on the side and a few of my good hobby projects include - DiceDB - a re-implementation of Redis in Go - Revine - a visual programming language for kids
