Storage Format

If you're working with Turso or need to understand how SQLite actually stores data on disk, this breaks down the file format internals. You get the page structure, B-tree organization, cell formats, overflow chains, and freelist management with actual byte offsets and diagrams. It points you to the relevant Rust files in Turso's codebase (btree.rs, pager.rs, sqlite3_ondisk.rs) and explains how table rows map to varints and serial types. Useful when you're debugging storage issues, optimizing page usage, or just curious why your database file is structured the way it is. The reference links to SQLite's official docs and Fly.io's internals writeup are solid next steps.
