Integrating a Data Warehouse and a Data Lake
FLORIAN VALEYE
STAFF DATA ENGINEER BACK MARKET
This conversation from the Open Source Summit in Spain provides valuable insights into the significance of Delta Lake, the role of Rust in data engineering, and the collaborative nature of open source communities.
The Delta Lake open source project integrates data lakes and data warehouses, a needed combination in this new age of scale-out data requiring reliability and controls.
A data lakehouse integrates the advanced data analytics and low-cost storage of a data lake with the performance and reliability of a data warehouse, said Florian Valeye, a data engineer with Back Market, in this episode of The New Stack Makers, recorded at the Open Source Summit in Bilbao, Spain, earlier this fall.
