# a partition index that designates a device. The number of bits kept
# from the hash is known as the partition power, and 2 to the partition
# power indicates the partition count. Partitioning the full MD5 hash
# ring allows other parts of the cluster to work in batches of items at
# once which ends up either more efficient or at least less complex than
# working with each item separately or the entire cluster all at once.
