Data Lakehouse¶
According to LaPlante (2021) a lakehouse combines elements of data lakes and data warehouses to build something new:
Lakehouses have similar data structures and data management features to data warehouses, but use the low-cost, flexible storage of data lakes.
Once you combine a data lake along with analytical infrastructure, the entire infrastructure can be called a data lakehouse (Inmon, Levins & Srivastava, 2021).
Overview¶
The article “Evolution to the Data Lakehouse” by Bill Inmon and Mary Levins (2021) provides an overview about the main challenges of current data architectures and how data lakhouse architectures address them:
After reading this article, you should be able to answer the following questions:
Questions
What are the challenges with current data architecture
How does the data lakehouse architecture solve the key challenges of current data architectures? Describe the key features.
Furthermore, make yourself familiar with the so called lambda-architecture, which many current architecures us:
