> Reads and writes in BookKeeper are asymmetric: a write request writes one
> entry, whereas a read request may read multiple requests. The current
> implementation of throttling only counts the number of read requests instead
> of counting the number of entries being read. Consequently, a few read
> requests reading a large number of entries each will spawn a large number of
> read-entry requests.
