You'll start with the strategic case for the STACKIT and Dremio partnership, then go deep on the technical internals: Dremio's distributed query engine, how Apache Arrow enables zero-copy, vectorized execution, and how query federation lets Dremio analyze data across multiple sources without ever moving it. From there the course builds the layers that make a lakehouse usable at organizational scale — a Universal Semantic Layer for consistent, business-friendly data products, Data Reflections to accelerate query performance dramatically without duplicating pipelines, and Apache Iceberg with Project Nessie for ACID guarantees, schema evolution, time travel, and Git-like branching over your data. Each of the three technical modules pairs the concept with a hands-on lab, so you leave able to both explain the architecture and actually operate it. ### What You'll Learn - Explain how Dremio's distributed engine and Apache Arrow deliver zero-copy, vectorized query performance - Run federated queries across multiple data sources without moving or duplicating data - Build a semantic layer and use Data Reflections to accelerate query performance - Apply Apache Iceberg and Project Nessie for ACID tables, schema evolution, and Git-style data branching ### Modules - Dremio Architecture and Apache Arrow - Query Federation and Semantic Layer - Reflections and Performance - Apache Iceberg and Project Nessie
