How to copy CosmosDb docs to Blob storage (each doc in single json file) with Azure Data Factory

Question

I\'m trying to backup my Cosmos Db storage using Azure Data Factory(v2). In general, it\'s doing its job, but I want to have each doc in Cosmos collection to correspond new json

Have you considered implementing this in a different way using Azure Functions? ADF is designed for moving data in bulk from one place to another and only generates a single file per collection.

You could consider having an Azure Function that is triggered when documents are added / updated in your collection and have the Azure Function output the document to blob storage. This should scale well and would be relatively easy to implement.
