WeSQL – An Innovative MySQL That Stores All Data on S3

In plain words

WeSQL is a MySQL variant designed to store all data on Amazon S3 instead of local storage. It is built for developers and organizations seeking cloud-native database solutions with scalable storage capabilities. The system combines MySQL compatibility with S3 integration, allowing users to leverage cloud storage infrastructure while maintaining familiar SQL interfaces. This approach aims to reduce storage costs and simplify data management for applications requiring flexible, distributed data infrastructure.

From the sources

WeSQL is an innovative MySQL distribution that adopts a compute-storage separation architecture, with storage backed by S3 (and S3-compatible systems). It can run on any cloud, ensuring no vendor lock-in. WeSQL has completely replaced MySQL’s traditional disk storage with S3. All MySQL data—binlogs, schemas, storage engine metadata, WAL, and data files—are entirely ( not partially! ) stored as objects in S3. The 11 nines of durability provided by S3 significantly enhances data reliability. Additionally, WeSQL can start from a clean, empty instance, connect to S3, load the data, and begin serving immediately with no additional setup required. It is ideal for users who need an easy-to-manage,…from github.com

  Turbolite – a SQLite VFS serving sub-250ms cold JOIN queries from S3Mar 2026 · github.com · ▲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…

  Lovable▲1,477

  Hey HN! Previous CERN physicist turned hacker here. We've developed a way to make AI coding actually work by systematically identifying and fixing places where LLMs typically fail in full-stack development. Today we're launching as Lovable (previously gptengineer.app) since it's such a big change. The problem? AI writing code typically make small mistakes and then get stuck. Those who tried know the frustration. We fixed most of this by mapping out where LLMs fail in full-stack dev and engineering around those pitfalls with prompt chains. Thanks to this, in all comparisons I found with: v0,…

  I wasn't quite sure if this qualified as "Show HN" given you can't really download it and try it out. However, dang said[0]: > If it's hardware or something that's not so easy to try out over the internet, find a different way to show how it actually works—a video, for example, or a detailed post with photos. Hopefully I did that? Additionally, I've put code and a detailed guide for the netboot computer management setup on GitHub: https://github.com/kentonv/lanparty Anyway, if this shouldn't have been Show HN, I apologize!
