>            Priority: Major

> Currently the API to list from a certain starting point is hidden inside {{{}AzureBlobFileSystemStore{}}}, and is hard to access. It'd be better to surface this up to places like {{AzureBlobFileSystem}} to make it easier to use. 
>  
> The API is useful in scenarios such as Delta Lake where transaction logs are always indexed sequentially. With this API, the listing in Delta no longer needs to listing the whole {{_delta_log}} directory but only a small subset.
