In this series of posts, I want to walk you through how to build a simple, persistent key-value store. We will be using an on-disk hashtable(also called external hashtable) to store the key-value mappings. In this post, I will explain hashtables briefly and an algorithm called linear hashing. In…
* Computers can be understoodExplains a mindset to understand systems by looking under the layers of abstraction. * Systems that defy detailed understanding: Follow-up to the above, listing some types of systems where it’s either impossible or just not worth it to understand from first-principles how the system works.
