EventProcessorClient and maintaining checkpoints in the Storage Account

[kobelev-dev]

Dear sirs,

Azure SDK contains abstract class Azure.Messaging.EventHubs.Primitives.CheckpointStore. This implies that users may want to create their own implementations. Great.

At the same time, from what I see, all constructors of the EventProcessorClient class use Azure.Storage.Blobs.BlobContainerClient as a parameter. This limits use of EventProcessorClient class only to the BlobCheckpointStore and not any other. I see that packages for other languages offer more, like Redis. So, my questions:

1. Am I missing something? Can it be that there is some trick that allows using EventProcessorClient with the custom check point sore? Note that I know about issue with multiple instances of EventProcessorClient and their need to have access to the same checkpoint store. My application for numerous reasons needs its own store. Is that possible?
2. Is there any other class that allows that? It may happen that I am looking at a wrong class. I am interested in .Net/C# solution.
