Personally, 10GB. It's a database of all "person pages" on English Wikipedia with some extracted text (infobox and sections) compressed using sqlite-zstd[1]. About 350k rows.<p>(I know this is "small" compared to what SQLite can handle, but it's the biggest I've worked with. Most of my SQLite databases are under 500MB).<p>[1]: <a href="https://github.com/phiresky/sqlite-zstd">https://github.com/phiresky/sqlite-zstd</a>
