Who publishes Lakenaut, and what it is not.

Who publishes this site

Lakenaut is an independent, personal project. It is not a company, and it sells nothing.

The contact address below reaches the person responsible for the content and for anything stored by the site.

No affiliation

Databricks, Unity Catalog, Lakeflow, Delta Lake, MLflow, Apache Spark and every other product name used here belong to their owners. Lakenaut is not affiliated with, endorsed by, or sponsored by Databricks Inc. Product names are used to say what the material is about, which is the only way to talk about them.

Nothing here is an official exam guide, an official certification, or a promise about what an exam contains. A badge from this site records that someone read a learning path; it is not a qualification and never claims to be one.

The content

The explanations are written here, from the public documentation, and rewritten in our own words. Where a page points at a source, the source is linked and belongs to whoever published it. If you believe something has been reproduced beyond fair quotation, write to the address below and it will be removed or rewritten.

Accuracy

The platform changes weekly and this site follows it as closely as it can, but it is not a support contract. Check the official documentation before doing anything irreversible in production. No liability is accepted for decisions taken on the strength of a page here.

Contact

This site is run by one person. Write to hello@lakenaut.dev for anything on this page — a copy of your data, a correction, a deletion, or a complaint.
