描述

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.

研究方向
Investigate how SquashFS can be used to compress SQLite databases in Docker containers built by `datasette package`. Examine the current Dockerfile generation in datasette (likely in `datasette/package.py`). Experiment with adding a SquashFS compression step for the database file and measure size reduction. Consider trade offs in read performance and compatibility. Review the linked article for inspiration and check for any existing discussions or PRs in the repository.
