ADF will use the ForEach activity to iterate through each configuration tables values passed on by the, activity, you can add all the activities that ADF should execute for each of the, values. Lastly, before moving to the pipeline activities, you should also create an additional dataset that references your target dataset.

Added Source (employee data) and Sink (department data) transformations Image is no longer available. Convert a timestamp from the source time zone to Universal Time Coordinated (UTC). To process data dynamically, we need to use a Lookup activity component to fetch the Configuration Table contents. To combine them back for ADF to process, you can use a simple script such as the below: It is as simple as that. (Totally obvious, right? Thanks for contributing an answer to Stack Overflow! Your solution should be dynamic enough that you save time on development and maintenance, but not so dynamic that it becomes difficult to understand. Each row has source and target table name and join condition on which i need to select data, I can understand that your row contains Source Table and Target Table name. Two datasets, one pipeline. In future posts I will show how you can parameterize all the other configuration values mentioned above so you can process any combination of them with the same dataset as well.
