What It Is

Hack MySQL is Daniel Nichter’s personal technical website, focused on MySQL, Go, software design, and engineering practices. The site states that the author has 20 years of MySQL experience and has published O’Reilly’s Efficient MySQL Performance. This is not a typical SaaS product; rather, it serves as a hub for technical articles, learning paths, talk materials, and the commercial tool mlrd.

Core Capabilities and Technical Depth

The most mature part of the site is its MySQL performance learning path. It is organized around query response time, indexes, data and access patterns, sharding, InnoDB metrics, replication, transaction locks, common challenges, cloud performance, and more. The content is aimed at software engineers rather than DBAs. Each topic includes context, key takeaways, pitfalls, internal articles, and external resources, with a clear documentation structure. The Go and software design content is also practical, covering topics such as designing extensible tools with factories, hooks, and context, accompanied by code snippets.

mlrd is the product that most resembles an actual “tool” in the site’s content. It claims to provide a DynamoDB-compatible API on top of MySQL, with the goals of reducing DynamoDB costs, mitigating vendor lock-in, and giving companies more freedom to inspect their data. The text clearly states that mlrd is not free or open source, but a commercial database tool currently in private beta. Details such as the API, SDKs, compatibility scope, deployment model, and SLA have not yet been disclosed.

Pricing and Commercialization

The website content is publicly readable; the book is sold through channels such as O’Reilly and Amazon. Pricing for mlrd has not yet been finalized. The author only says it is expected to be significantly cheaper than DynamoDB spending for some companies, and mentions that PlanetScale + mlrd could be 40–60% cheaper than DynamoDB, but this is not an official pricing table.

Pros, Cons, and Who It’s For

Its strengths are strong technical depth and well-designed guided learning paths, especially for backend engineers using MySQL, performance troubleshooting practitioners, and Go tool developers. The downside is the lack of productization details: mlrd still lacks public documentation, a trial process, payment methods, enterprise support information, and compatibility notes. If you want to systematically improve your ability to reason about MySQL performance, Hack MySQL is well worth reading. If you need to immediately purchase a production-grade alternative to DynamoDB, you should contact the author for further evaluation.

Access from China

The crawled text does not provide information about access from mainland China, payment options, or mirrors, so this is unknown. Alternative references include the official MySQL documentation, the Percona blog and tools, PlanetScale documentation, and AWS DynamoDB documentation.
