Description

Inspired by this article: https://cldellow.com/2018/06/22/sqlite-parquet-vtable.html#sqlite-database-indexed--squashed

https://en.wikipedia.org/wiki/SquashFS is "a compressed read-only file system for Linux" - which means it could be a really nice fit for Datasette and its read-only SQLite databases.

It would be interesting to explore a Dockerfile recipe that used SquashFS to compress the SQLite database file that was bundled up by datasette package and friends.

Contributor guide

Research direction
Research SquashFS integration with Docker: create a Dockerfile that uses mksquashfs to compress SQLite databases, test size reduction and compatibility with Datasette's read only access. Explore existing tools like 'squashfs tools' and Docker's ability to mount SquashFS images.
