    If this is required only for if can you move it inside if ? I know that control will not
reach that line if it enters else but I think moving inside if will be more readable

    result can be null isn't. get(0) will throw NPE if result is null. Check if result is
null before trying to access it. Do the same for FileSystemStorage.

Falcon processes or feed replication provides status on instances. When the instance status
is WAITING for input, users have difficulty in identifying what feed is missing. In general
it would very helpful to users to get feed availability status natively through falcon.
