An Azure service for ingesting, preparing, and transforming data at scale.
That's not a recommended approach.
In a data factory, you have 5 pipelines. You can't link these 5 individual pipelines to 5 individual repositories as far as I know.
Ideal way is to create a development data factory, link it to a repository and all the 5 pipelines, related datasets and linked services code gets saved to that single linked repository.
