> Redis state iterator iterates pending prepare -> pending commit -> external storage (state) sequentially. While iterating, more of them are subject to change, so it can provide inconsistent result.
> While we can't provide consistent result (since states are changing continuously), at least iterator needs to provide same key only once.
