I am trying to design a stream a data analytics project using   functions -->  event hub -->  storage --> Azure factory --> databricks -->  SQL server.
What I am strugging with at the moment is the idea about how to optimize "data retrieval" to feed my ETL process on Azure Databricks.
with this I am going to handle lots of incoming file during different period of time and  I an using. function to create event of the file as it comes and sent o blob storage then I put  the data to azure data factory and then it comes to databricks, all this process is taking ample amount of time and  creating delay in full process
