Hi,

One way is to write the json with Databricks in a azure storage account:

https://docs.azuredatabricks.net/spark/latest/data-sources/azure/azure-storage.html

Then, in the Azure Function you can access to the storage account:

https://docs.microsoft.com/en-us/azure/azure-functions/functions-bindings-storage-blob

You can orchestrate this with Azure Data Factory (https://docs.microsoft.com/en-us/azure/data-factory/transform-data-using-databricks-notebook):

1) Call Databricks activity that will produce the JSON

2) If first activity is successful, call azure function activity
