SQLite Internals: Pages & B-trees

The text discusses SQLite, a lightweight database engine that is simple and reliable due to its constrained size and feature set. It explains how SQLite encodes data in its record format using variable-length integers (varints) for efficient storage of integers and types. The text also delves into the use of pages and b-trees for efficient updates, insertions, and searches within a database. Understanding these internals can help developers feel more comfortable with SQLite and confidently design applications using it.
