azure - Get list of blobs in container added after some date

Question

I need to read blobs from a azure container which are added after a particular date. Basically, I have a windows service which runs once a day and gets the list of blobs added after the first run. I do not see any such option in CloudBlobContainer.ListBlobsSegmentedAsync function or via the Get Blob REST API call. I could think of only one option- have timestamp in the filename and filter by prefix but would like to know other better options to achieve this.

Unfortunately there's very limited server-side filtering available in Azure Blob Storage and only filtering allowed today is by blob name prefix.

One solution to your problem is list all blobs in a container. Each blob has a property called Created Date/Time which tells you when the blob was first created (there's another property called Last Modified as well).

When you have the list, you can filter on the client side by this Created Date/Time property to get the desired list of blobs.
