Known issue - Refreshes have slow performance and timeouts for Dataflows Gen2 with CI/CD

When you refresh a Dataflow Gen2 with CI/CD capability in Fabric, you might notice that the refresh runs slower or times out when compared with the same Dataflow 2.0 without CI/CD.

Status: Open

Product Experience: Data Factory

Symptoms

Dataflow refresh runs for a long period when compared with the same Dataflow Gen2 without CI/CD capabilities. You might notice the dataflow refresh takes too long and times out. This issue happens on workspaces where no new CI/CD enabled dataflow were created after May 24, 2025.

Solutions and workarounds

To work around this issue, create a new Dataflow Gen2 with CI/CD capabilities in the same workspace of the dataflow where you see the performance issue. Wait for 10 minutes and then run the dataflow refresh again with better performance.
