class ConsistencyLevel:
  """
  The ConsistencyLevel is an enum that controls both read and write
  behavior based on the ReplicationFactor of the keyspace.  The
  different consistency levels have different meanings, depending on
  if you're doing a write or read operation.

  If W + R > ReplicationFactor, where W is the number of nodes to
  block for on write, and R the number to block for on reads, you
  will have strongly consistent behavior; that is, readers will
  always see the most recent write. Of these, the most interesting is
  to do QUORUM reads and writes, which gives you consistency while
  still allowing availability in the face of node failures up to half
  of <ReplicationFactor>. Of course if latency is more important than
  consistency then you can use lower values for either or both.

  Some ConsistencyLevels (ONE, TWO, THREE) refer to a specific number
  of replicas rather than a logical concept that adjusts
  automatically with the replication factor.  Of these, only ONE is
  commonly used; TWO and (even more rarely) THREE are only useful
  when you care more about guaranteeing a certain level of
  durability, than consistency.

  Write consistency levels make the following guarantees before reporting success to the client:
    ANY          Ensure that the write has been written once somewhere, including possibly being hinted in a non-target node.
    ONE          Ensure that the write has been written to at least 1 node's commit log and memory table
    TWO          Ensure that the write has been written to at least 2 node's commit log and memory table
    THREE        Ensure that the write has been written to at least 3 node's commit log and memory table
    QUORUM       Ensure that the write has been written to <ReplicationFactor> / 2 + 1 nodes
    LOCAL_QUORUM Ensure that the write has been written to <ReplicationFactor> / 2 + 1 nodes, within the local datacenter (requires NetworkTopologyStrategy)
    EACH_QUORUM  Ensure that the write has been written to <ReplicationFactor> / 2 + 1 nodes in each datacenter (requires NetworkTopologyStrategy)
    ALL          Ensure that the write is written to <code>&lt;ReplicationFactor&gt;</code> nodes before responding to the client.

  Read consistency levels make the following guarantees before returning successful results to the client:
    ANY          Not supported. You probably want ONE instead.
    ONE          Returns the record obtained from a single replica.
    TWO          Returns the record with the most recent timestamp once two replicas have replied.
    THREE        Returns the record with the most recent timestamp once three replicas have replied.
    QUORUM       Returns the record with the most recent timestamp once a majority of replicas have replied.
    LOCAL_QUORUM Returns the record with the most recent timestamp once a majority of replicas within the local datacenter have replied.
    EACH_QUORUM  Returns the record with the most recent timestamp once a majority of replicas within each datacenter have replied.
    ALL          Returns the record with the most recent timestamp once all replicas have replied (implies no replica may be down)..
