Fabric Dataflow Gen2 (the Dataflow item)

Dataflow Gen2 is the Power Query item in Fabric Data Factory: a low-code transformation surface that ingests, reshapes and loads data without code. This skill covers the item as Git and REST see it — the files on disk, the API that writes them, and the limits that decide whether a design works.

The product name and the item type differ, and both are load-bearing. Everything a user types says Dataflow Gen2; the .platform file, the ItemType enum and the REST namespace all say Dataflow. The Git folder is <display name>.Dataflow.

"Gen2" no longer implies a choice. Since April 2026 the option to create a Dataflow Gen2 without CI/CD and Git support is gone, and every new item is created with it. Items created before that keep working, and the docs still split behaviour by which kind you have — so when a page says "applies to Dataflow Gen2 with CI/CD support", that is now the default case and the non-CI/CD case is legacy.

1. What is on disk

Serialization mechanics — EOF newlines, CRLF/LF, .gitattributes — are in the fabric-git-serialization rule, which globs this folder too. M style conventions are the coding-m rule's, which globs mashup.pq. Neither is restated here.
