| 8 | **What:** Dataflows Gen2 — modern, scalable ETL via Power Query in Fabric. | ||
| 9 | **Strength:** No-/low-code, native Lakehouse integration, incremental refresh. | ||

| 12 | == What are Dataflows Gen2? == | ||
| 13 | |||
| 14 | **Dataflows Gen2** are a **modern, scalable way** to **ingest, transform, and load data** into Microsoft Fabric. They allow users to build **reusable ETL pipelines** using familiar **Power Query** experiences, while integrating natively with **Lakehouse**, **Warehouse**, and other Fabric destinations. | ||
| 15 | |||
| 16 | == 🔑 Key Features == | ||
| 17 | |||
| 18 | |=Feature|=What it gives you | ||
| 19 | |**Power Query Interface**|Build transformations using a no-code or low-code experience, with full support for **M language**. | ||
| 20 | |**Direct Lakehouse Integration**|Write output directly to Lakehouse tables in **Parquet** format, enabling seamless analytics and reporting. | ||
| 21 | |**Incremental Refresh**|Filter out previously processed data — only **new** or **changed** rows are loaded on each refresh. | ||
| 22 | |||
| 23 | == 🧩 Common Use Cases == | ||
| 24 | |||
| 25 | * Loading **structured data from SharePoint** into Lakehouse | ||
| 26 | * Transforming **Excel-based reports** into analytics-ready formats | ||
| 27 | * **Filtering** and **deduplicating** data before ingestion | ||
| 28 | * Automating **daily refreshes** for operational dashboards | ||
| 29 | |||
| 30 | == Dataflow Gen2 vs. Pipelines vs. Notebooks == | ||
