Learn by Building Redis with Ruby
Learn all about Redis and how it works under the hood by building your own clone.
What you'll learn
In this course we build a Redis clone from scratch, using Ruby. We will implement all the major features, including the data structures, transactions, persistence, and more. Along the way we'll also learn how Redis uses Unix sockets and process management to better understand how it operates at the system level. By the end of this course you will have a better understanding of how Redis works, allowing you to make better decisions about how and when to use it.
