How can I run multiple instances of all the values going in the FOREACH simultaneously?

Ishank22 you can use the ForEach activity to run all the values the Lookup widget passes simultaneously.
- Create a Linked Service and Dataset.
- Create a parameter of relativeURL with respective values.
- Read the data by the Lookup activity, and use the code below to iterate over the values inside the ForEach activity using their indexes.

@range(0,length(pipeline().parameters.relativeURL))

Unfortunately, nested loops are not allowed in Azure Data Factory.

 Let me know if this works for you. @ me in replies, or I'll lose your thread!!!
