Dataflow inside Dataflow

Hi Anonymous,
Thanks for reaching out to the Microsoft Fabric Community Forum.

Also, great insights from bhanu_gautam appreciate your contribution.

To add more details:

• Microsoft Fabric Dataflows are used within Fabric for big data scenarios, integrating with Lakehouse and Data Warehouse.
• Power Platform Dataflows work across Power BI, Power Apps, and Power Automate, storing data in Azure Data Lake Gen2.
• Power BI Dataflows are an older version of Power BI dataflows and are not recommended for new implementations.

Is it a good practice to use one dataflow inside another?

Yes, but with caution. This is called dataflow chaining, and while it has benefits, it also comes with some risks.

Pros:

• You can standardize data transformations across multiple reports.
• Breaking large datasets into multiple stages can improve processing efficiency.
• Ensures all reports use the same cleaned and transformed data.

Cons:

• Each additional dataflow adds another processing step.
• If the first dataflow fails or changes, it can break downstream dataflows.
• Intermediate results are stored, which may consume more OneLake or Azure Data Lake storage.

Best practices for chaining dataflows:

• Limit chaining to 1-2 levels to avoid long refresh times.
• Use incremental refresh to optimize performance.
• Monitor dependencies to prevent failures when source dataflows change.
• Optimize transformations early to reduce redundant processing in later stages.

If your use case involves big data processing and advanced transformations, Fabric Dataflows are the best option.
