Lakehouse Architecture

Concepts: paDataLake

What They Want to Hear 'A lakehouse is four layers: storage (S3/GCS, cheap and durable), format (Delta or Iceberg for ACID and time travel), compute (Spark or Trino, separated from storage so you scale independently), and governance (Unity Catalog or Polaris for access control, lineage, and audit). The key difference from a lake with a query engine: the table format layer provides warehouse-like guarantees without the warehouse cost.'
