A lamer's blog

Few months after my last post (already 2 years ago!) I landed my first job. My free time started running very low together with my energies, even though I was in full remote 9 to 5.

Thanks to SQLite VFS abstraction, it is possible to implement your own file system on which SQLite parks data and structures. Inspired by Phiresky's sql.js-httpvfs which uses HTTP Range requests to lazy load blocks of storage from a static web server, I changed few lines of code to point the VFS read() calls to a database seeded by peers as a torrent. A 300 MiB db with 2 million records can be queried from seeders for full text searches in less than 1 MiB traffic with the BitTorrent protocol, all inside the browser, in a static website.

Since IPFS, a p2p network for storing and retrieving files, has a javascript implementation that runs on browsers, it can be used in torrent websites to retrieve a small database from peers instead of the server. A .sqlite file, 13 MB in size containing around 135,000 records, can be retrieved in 8 seconds from the IPFS network using a 100 Mbit connection. Since the database object is small enough to be cached by the browser, subsequent visits take zero.
