A self-paced architecture course on the lakehouse pattern — open table formats over object storage, with warehouse guarantees. It covers six stages: what the lakehouse actually solves, how open table formats work underneath, layout and performance, the medallion pattern and modelling, streaming and incremental processing, and governance, cost and operating the platform.

The focus is the mechanics beneath the marketing — what a table format is doing on disk, why that gives you transactions, and where each format’s trade-offs actually bite. Tech Skills Library is independent and issues no certification or credential.
