Architecting an Apache Iceberg Lakehouse shows you how to design an open, scalable, and cost-effective lakehouse platform with Apache Iceberg. More than a set of blueprints, the book explains the reasoning behind the architecture. You’ll build a mini lakehouse by ingesting sales and marketing data from PostgreSQL into Iceberg tables with Apache Spark and then create interactive dashboards in Apache Superset. You’ll appreciate expert Alex Merced’s real-world insights about operating an Iceberg lakehouse.
