Covers provisioning a Databricks workspace on AWS with customer-managed VPC, configuring KurrentDB Cloud IP allowlists, verifying layered connectivity, setting up Unity Catalog with medallion schemas (Bronze/Silver/Gold), and building a daily analytics read model that materialises a Flight SQL query into a Delta table. Includes a complete loan-origination example with multi-event-type FULL OUTER JOINs executed on the KurrentDB DuckDB-backed engine, Python ADBC driver usage, and Databricks Workflow scheduling. Part 2 extends this into incremental ingestion with high-water-mark tracking. ## Full article daily.dev links to this article rather than hosting it.
