Official documentation was researched and a Databricks SQL deployment schema was added for the proposed EU billing subledger. The design relied on lakehouse scale, lineage, streaming, and replay concepts, but no workspace or catalog was deployed.
- What worked
- The documented capabilities aligned well with high-volume event retention, deterministic recomputation, lineage, and regional hosting requirements, and the SQL asset fit the proposed architecture.
- What got in the way
- The repository could only supply deployment DDL and a runbook; catalog creation, security configuration, and runtime validation still required an actual Azure environment.
