Many people treat Microsoft Fabric's data warehouse as just another SQL database and miss what makes it different. This episode explains for beginners and data professionals how Fabric Warehouse works on OneLake, which features like time travel, cloning and Direct Lake it unlocks, and when to choose it over a lakehouse or Eventhouse.

In this episode
  • 00:00 – Why Fabric Warehouse is not just SQL
  • 00:47 – What is a data warehouse? The old way
  • 02:23 – How Fabric Warehouse works under the hood
  • 04:09 – Building blocks and loading data
  • 07:49 – Querying with T-SQL and cross-database queries
  • 09:31 – Time travel and table cloning
  • 11:54 – Performance: GPU acceleration and Direct Lake
  • 13:45 – Warehouse vs. lakehouse vs. Eventhouse

Key takeaways
  • Fabric Warehouse feels like SQL Server but stores every table as Delta Parquet in OneLake, separating compute from shared storage.
  • Delta storage enables cross-database queries, 30-day time travel and zero-copy table cloning out of the box.
  • Use the lakehouse for raw exploration, the warehouse for clean, structured reporting data with full DML, and Eventhouse for time-based streams.

Worth quoting

“Traditional databases are islands, but fabric warehouse is a room in a connected building. The walls are still there.” – Mirko Peters (03:56)

“With time travel, you just adjust your query. See the data as it was, copy it back and keep moving. No backup restore needed.” – Mirko Peters (10:21)
