Refresh Materialized Lake View activity in Fabric Data Factory pipelines

The Refresh Materialized Lake View activity refreshes a materialized lake view as part of a Fabric pipeline. Materialized lake views are precomputed, cached result sets stored in a Lakehouse that speed up downstream queries. Use this activity to keep cached results in sync with your source data after ingestion, transformation, or maintenance operations.

Use the Refresh Materialized Lake View activity when you want to:

  • Refresh a materialized lake view on demand or on a schedule.
  • Refresh views after upstream activities like Copy, Notebook, or Lakehouse Maintenance.
  • Include lake view refreshes in end-to-end pipeline orchestration.
