title: Azure Data Factory Only Retrieve New Blob files from Blob Storage
body: <p>I am currently copying blob files from an Azure Blob storage to an Azure SQL Database. It is scheduled to run every 15 minutes but each time it runs it repeatedly imports all blob files. I would rather like to configure it so that it only imports if any new files have arrived into the Blob storage. One thing to note is that the files do not have a date time stamp. All files are present in a single blob container. New files are added to the same blob container. Do you know how to configure this?</p>
