Microsoft Fabric's integration with Azure Data security features helps maintain compliance and protect sensitive data during ingest and processing.

Are there cost implications when using dataflow gen2 in Microsoft Fabric?

Costs depend on workload size, compute used during transformations, storage in Fabric data destinations and frequency of refreshes. Planning medallion architectures, optimizing queries in the Power Query Editor, and monitoring workloads can help control costs. Refer to Microsoft Learn and pricing documentation for detailed estimates.

How can I get started learning dataflows gen2 and where can I find tutorials?

Start with Microsoft Learn modules and the Microsoft Fabric blog for step-by-step tutorials, best practices and sample scenarios. Hands-on labs in Learn, documentation for the Power Query Editor and community articles will help you build pipelines, include a dataflow in workspaces and ingest data into Fabric.

Does Fabric support hybrid scenarios with on-premises data sources?

Yes, Fabric dataflows gen2 can connect to on-premises data sources using supported gateways or hybrid connectors, enabling you to get data from legacy systems and load the data into Fabric for further processing while maintaining security and compliance controls.
