Data Lakehouse

An architecture that adds warehouse features such as ACID transactions, schema enforcement and fast SQL to low-cost data lake storage using open table formats.

Definition

Lakehouses use formats such as Delta Lake, Apache Iceberg or Hudi on object storage, which lets BI, SQL, streaming and ML workloads share one copy of the data. Databricks, Microsoft Fabric, Snowflake (Iceberg tables) and BigLake on Google Cloud all implement lakehouse patterns.

Exam tip

Lakehouse = data lake storage + warehouse reliability (ACID, schema) through an open table format.
