Dataflow gen2 - Staging Storage cost confusion
Hi Max_701,
Your understanding is correct: with staging enabled in Dataflow Gen2, intermediate data is stored in OneLake and billed separately from your Fabric capacity, based on standard Azure Data Lake Storage Gen2 rates (such as about $0.023/GB/month for hot storage in most regions). Fabric capacity (F-SKU) only covers compute, not storage. Additionally, enabling staging may increase compute usage, as Dataflow Gen2 could use High Scale Dataflow or SQL engine compute during refresh, which is billed against your Fabric capacity. This setup does not result in double billing; instead, compute and storage are billed as separate components. Staged data is billed for storage in the same way as any other Lakehouse or Warehouse data.
Thank you.
