For people who enjoy this article I recommend reading the two-parter “How does SQLite work?” [1] [2] by Julia Evans. It too is an exploration into the inner workings but diving deeper into code. And for those interested in more details on b-trees, there’s “The Ubiquitous B-Tree” by Douglas Cramer which I enjoyed a lot.
