Doug Database ingestion architecture demonstrates four distinct pathways from AWS Aurora PostgreSQL to Databricks Lakehouse and Azure Synapse Analytics. Data flows from a private Aurora instance in a VPC through four options: Direct LH Federation for live query mesh, PostgreSQL Preview with managed CDC, Direct JDBC with custom Spark ETL, or Synapse Ingestion via the BAW team pipeline. This multi-path design lets data teams choose between real-time federation, change data capture, custom transformation, or managed ingestion based on latency and complexity requirements. Fork this diagram to customize ingestion paths, adjust network topology, or document your organization's data movement strategy across AWS and Azure.
