DocumentDb Change Feed event type?

Is there a way to determine the operation (add/update/delete) that produced change feed entry?

My tests are running using the example provided here but I've been unsuccessful identifying the originating action.

To distinguish between creates and updates, you can add a version number for your document. That way, document creates in the change feed will have version = 1, but updates will be 2 or higher.

To track deletes, the best approach is to use DocumentDB's TTL capability. That is, you mark documents with TTL = saym 1 hour. Then you can treat all documents with TTL value set in the change feed as deletes.
