Turbolite – a SQLite VFS serving sub-250ms cold JOIN queries from S3▲185
I built a SQLite VFS in Rust that serves cold queries directly from S3 with sub-second performance, and often much faster. It’s called turbolite. It is experimental, buggy, and may corrupt data. I would not trust it with anything important yet. I wanted to explore whether object storage has gotten fast enough to support embedded databases over cloud storage. Filesystems reward tiny random reads and in-place mutation. S3 rewards fewer requests, bigger transfers, immutable objects, and aggressively parallel operations where bandwidth is often the real constraint. This was explicitly inspired…

Base, an SQLite database editor for macOS▲693
I recently released v3 of Base, my SQLite editor for macOS. The goal of this app is to provide a comfortable native GUI for SQLite, without it turning into a massive IDE-style app. The coolest features are - That it can handle full altering of tables, which is quite finicky to do manually with SQLite. - It has a more detailed display of column constraints than most editors. Each constraint is shown as an icon if active, with full details available on clicking the icon. This update also adds support for attaching databases, which is a bit fiddly with macOS sandboxing. I'd love to hear any…

Distributed SQLite on FoundationDB▲150
Hello HN! I'm building mvsqlite, a distributed variant of SQLite with MVCC transactions, that runs on FoundationDB. It is a drop-in replacement that just needs an `LD_PRELOAD` for existing applications using SQLite. I made this because Blueboat (https://github.com/losfair/blueboat) needs a native SQL interface to persistent data. Apparently, just providing a transactional key-value store isn’t enough - it is more easy and efficient to build complex business logic on an SQL database, and it seems necessary to bring a self-hostable distributed SQL DB onto the platform.…

Embed an SQLite database in your PostgreSQL table▲180
pglite-fusion is a PostgreSQL extension that allows you to embed SQLite databases into your PostgreSQL tables by enabling the creation of columns with the `SQLITE` type. This means every row in the table can have an embedded SQLite database. In addition to the PostgreSQL `SQLITE` type, pglite-fusion provides the `query_sqlite`` function for querying SQLite databases and the `execute_sqlite` function for updating them. Additional functions are listed in the project’s README. The pglite-fusion extension is written in Rust using the pgrx framework [1]. ---- Implementation Details The PostgreSQL…

Roast my SQLite encryption at-rest▲99
SQLite encryption at-rest is a hot requested feature of both the “default” CGo driver [1] and the transpiled alternative driver [2]. So, this is a feature I wanted to bring to my own Wasm based Go driver/bindings [3]. Open-source SQLite encryption extensions have had a troubled last few years. For whatever reason, in 2020 the (undocumented) feature that made it easy to offer page-level encryption was removed [4]. Some solutions are stuck with SQLite 3.31.1, but Ulrich Telle stepped up with a VFS approach [5]. Still, their solution seemed harder than something I'd want to maintain, as it…

DBOS transact – Ultra-lightweight durable execution in Python▲89
Hi HN - DBOS CEO here with the co-founders of DBOS, Peter (KraftyOne) and Qian (qianli_cs). The company started as a research project of Stanford and MIT, and Peter and Qian were advised by Mike Stonebreaker, the creator of Postgres, and Matei Zaharia, the creator of Spark. They believe so strongly in reliable, serverless compute that they started a company (with Mike) to bring it to the world! Today we want to share our brand new Python library providing ultra-lightweight durable execution. https://github.com/dbos-inc/dbos-transact-py Durable execution means your program…

Doculite – Use SQLite as a Document Database▲160
Hi! As I was working on a side project, I noticed I wanted to use SQLite like a Document Database on the server. So I built Doculite. DocuLite lets you use SQLite like Firebase Firestore. It's written in Typescript and an adapter on top of sqlite3 and sqlite. Reasons: 1) Using an SQL Database meant having less flexibility and iterating slower. 2) Alternative, proven Document Databases only offered client/server support. 3) No network. Having SQLite server-side next to the application is extremely fast. 4) Replicating Firestore's API makes it easy to use. 5) Listeners and real-time…
