SQLite Vacuum: A Comprehensive Guide

SQLite, a lightweight and self-contained database management solution, is widely used in various applications, from mobile apps to desktop software. One essential maintenance task for SQLite databases is the VACUUM command, which plays a crucial role in optimizing database performance and managing storage space. In this article, we will delve into the details of what SQLite Vacuum is, why it is important, and how to effectively use it.
