Chapter 10: Lakehouse Technology Evaluation

Chapter’s Summary

The chapter of the book provides an in-depth analysis of Data Lakehouse technology, focusing on various implementation options such as cloud-managed and self-managed deployments, major cloud platforms like AWS, Azure, and GCP, and key open source tools and commercial solutions. It explores the trade-offs between cloud-managed and self-managed lakehouses, emphasizing the balance between ease of management, scalability, and control. The chapter evaluates cloud platforms based on their storage, processing, querying, and governance capabilities, and delves into the strengths and use cases of open source tools like Delta Lake, Apache Spark, Hive, Presto, and Airflow. Furthermore, it assesses commercial solutions like Databricks, Snowflake, and Microsoft Fabric, highlighting their support, integration, and advanced functionalities while cautioning about potential issues like vendor lock-in and cost.

The chapter emphasizes the importance of aligning the choice of a Data Lakehouse with an organization’s specific data strategy, considering factors like cost, performance, regulatory requirements, and in-house expertise. It suggests a holistic approach, weighing both open source and commercial options to find the right mix of flexibility, scalability, and support. Cloud-managed lakehouses are noted for their ease of use and advanced features, but with higher operational costs and less control, whereas self-managed lakehouses offer more customization and potentially lower long-term costs but require more resources to manage. The chapter concludes by underlining the need for flexibility in technology decisions, allowing organizations to adapt to the evolving data landscape.
