    Get the most recent last batch and the ID (strictly less than the input ID) The "Last" is the stream with only the newest value for each key.

    Reads the key log for this batch.

    Reads the key log for this batch. By key log we mean a log of time, key and value when the key was written to. This is an associative operation and sufficient to scedule the service. This only has the keys that changed value during this batch.
