Demystifying the Data Lakehouse in Microsoft Fabric

Proposed session for SQLBits 2026

TL; DR

Confused by the Data Lakehouse concept? Learn what it really is, how Fabric implements it, and how it changes the way you build modern analytics solutions.

Session Details

The Data Lakehouse has become one of the most talked-about architectural patterns in analytics - but what is it really, and how does Microsoft Fabric bring it to life?

This session breaks down the Lakehouse concept in clear, practical terms. We’ll explore how decoupled storage and compute work in Fabric, how Delta Lake enables reliability at scale, and how the medallion architecture shapes ingestion, transformation, and modeling best practices. You’ll learn when to use SQL, when to use Spark, and why the Lakehouse approach is so powerful for modern BI and data engineering teams.

If you want a solid understanding of how to design and deliver Lakehouse solutions on Fabric - this session demystifies it all.

3 things you'll get out of this session

Understand the core principles of the Lakehouse architecture Learn how Fabric implements storage/compute decoupling See how Delta Lake enables reliability and ACID guarantees Know when to use SQL or Spark for different tasks Build a clear mental model of the Fabric medallion architecture
