- Not fully; push-down transforms rise, but curated processing, data contracts, and quality checks remain essential.
5. Are Unity Catalog and Delta constraints sufficient for compliance?
- They form a solid base; enterprises still add segregation of duties, sensitive data workflows, and audit evidence management.
6. Will AI copilots reduce headcount in data engineering?
- Expect capacity shifts over cuts; copilots accelerate delivery while oversight, testing, and governance remain human-critical.
7. Can small enterprises adopt Databricks without large teams?
