![]() Saying that,you can invoke the transparent row-level compression function several times on the same table with different columns to compress. After that we will enable the transparent row-level compression of the 'body' column, the column that keeps the bulk of the text of the 'notes' table. Having got hold of the CLI it's time to execute it to load both the library and sample database. While you can build it manually, why go to that trouble when someone has already done it for you? Hop over to the SQLite shell builder Github repo and download the latest 64-bit release for Windows (Ubuntu, MacOS as well). Of course your use case might be different the library's main use case example online showcases compressing a database with 7 million book entries in JSON format, and does so by reducing its size from 2.2GB to 550KB!īut in order to get to that, the first hurdle was to find the 64-bit version of sqlite's CLI, sqlite3, since the official build is offered only in 32-bit, and since zstd is a 64-bit library it needed the corresponding version. As such the number of pages I dump into Joplin accumulates and the size of the database increases. Since I'm a person with a wide array of interests, when I find something interesting I keep a copy of it. It is like that because Joplin allows you to scrape any web page you encounter and store it as markdown inside the database. It is true that that number sounds extravagant. The sample database.sqlite is 2.6 GB in size.Some would say 'what kind of notes do you have that occupy that much space?'. Well work with Windows because it offers a more straightforward experience. As a proof of concept and walkthrough of the tool, I'll work with a sample database used by the Joplin note taking app. 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. 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. This has changed with the Rust-based library, sqlite-zstd which promises to: SQLite doesn’t have any compression features. However, there are few built-in functions compared to PostgreSQL or Oracle. Meet sqlite-zstd, a Rust library that compresses your database many fold, leading to great savings in size while conserving its search capabilities intact.Īs pointed out in "In Praise Of SQLite", SQLite is not a toy database:ĭespite 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. Use Rust To Reduce The Size Of Your SQLite Database
