Use Rust To Reduce The Size Of Your SQLite Database

 Meet sqlite-zstd, a Rust library that compresses your database many fold, leading to great savings in size while conserving its search capabilities intact.

As pointed out in "In Praise Of SQLite", SQLite is not a toy database:

Despite its compact size and absence of the client server model, SQLite is a RDBMS with all the features that make something relational - that is tables, indexes, constraints, triggers, transactions and the like. However, there are few built-in functions compared to PostgreSQL or Oracle. 

SQLite doesn’t have any compression features. This has changed with the Rust-based library, sqlite-zstd which promises to:

provide transparent dictionary-based row-level compression that allows compressing a sqlite database's entries almost as well as if you were compressing the whole DB file, while at the same time retaining random access.

Suffice it to say that we are all aware of the benefits of compressing data, be it that of a PDF document, a humble ZIP file or in this case a database. As a proof of concept and walkthrough of the tool, I'll work with a sample database used by the Joplin note taking app. Well work with Windows because it offers a more straightforward experience.
