The open-source web application server, Clace, has opted for SQLite as its storage solution for static content. This decision provides several benefits, including atomic version changes, deployment rollbacks, file de-duplication across versions and apps, easy backups, and content hashing. While the use of a database may require an API interface for uploading files, it offers improved performance and features compared to traditional file system-based approaches.
