Use a foreach activity to iterate over the retrieved data
Perform the required operations on the data within the foreach activity
Write the output to the desired destination
My suggestion for implementation in Azure Data Factory v2 is to use the Mapping Data Flow feature.
Utilize Mapping Data Flow for complex data transformations
Take advantage of the visual interface to design and debug data flows
Leverage the built-in data integration capabilities with other Azure services
Use data flow parameters and expressions for dynamic transformations
Monitor and optimize data flow performance using dat
