Rails on SQLite: A Double-Edged Sword

André Arko, a long-time Ruby open source contributor, shares his experience building a Rails application using SQLite. While SQLite simplifies deployment and reduces costs due to its embedded nature, it introduces unique challenges. The article details these challenges, including data persistence, concurrency control, and high availability, offering solutions like persistent storage, WAL mode, multiple database files, and tools like Litestream and LiteFS. Arko concludes that SQLite offers exciting possibilities for building efficient and simple Rails apps but requires careful consideration of its limitations.
