 - **Capacity** - The number of buckets in the hash table.  Producers should
   maintain a load factor of no greater than ``2/3*Capacity+1``.

 - **Present Bit Vector** - A serialized bit vector which contains information
   about which buckets have valid values.  If the bucket has a value, the
   corresponding bit will be set, and if the bucket doesn't have a value (either
   because the bucket is empty or because the value is a tombstone value) the bit
   will be unset.

 - **Deleted Bit Vector** - A serialized bit vector which contains information
   about which buckets have tombstone values.  If the entry in this bucket is
   deleted, the bit will be set, otherwise it will be unset.
