Databricks Data Engineer Professional

Important

What changed in the November 30, 2025 exam guide

  • Restructured from 5 broad topics into 10 explicitly weighted domains
  • Data Sharing and Federation (Delta Sharing, Lakehouse Federation) is now a first-class domain (5 %)
  • Data Modelling is now a first-class domain (6 %) — renamed and re-weighted; previously a top-level section in the older blueprint
  • Stronger emphasis on Cost & Performance Optimization (13 %)
  • Pass / fail — the Nov 30, 2025 exam guide does not publish a numeric passing score

The official source of truth: Databricks Certified Data Engineer Professional (and the November 30, 2025 exam guide PDF). The folder structure in this guide now matches the official 10-domain blueprint 1 : 1.
