Syllable breakdown
Dictionary meaning
a modern data architecture paradigm that combines the flexibility and low cost of a data lake (raw storage of all data types) with the performance, reliability, and ACID transaction support of a data warehouse; data is stored in open formats (such as Delta Lake, Apache Iceberg, or Apache Hudi) directly on cloud object storage, enabling both BI queries and machine learning workloads on the same data without duplication; coined by Databricks researchers in a 2021 paper; key implementations include Delta Lake (Databricks), Apache Iceberg (Netflix), and Apache Hudi (Uber)
Examples
- The lakehouse architecture eliminated the need to maintain separate data lake and data warehouse systems.
- Delta Lake's lakehouse approach brought ACID transactions to what was previously a 'data swamp'.
Synonyms: open data lakehouse, data lakehouse
