Architecting a HIPAA-Compliant Streaming FHIR Lakehouse on Databricks

The comprehensive engineering blueprint for ingesting, normalizing, and querying real-time HL7 FHIR R4 bundles on Databricks and Delta Lake. Covers schema flattening, LOINC/SNOMED terminology mapping, probabilistic Master Patient Index (EMPI) resolution, and OHDSI OMOP CDM harmonization.

Key Highlight: FHIR R4 resources contain deeply nested JSON arrays (extensions, codings, components) that degrade standard SQL performance without flattening.
