### describe_ring

    java.util.List<TokenRange> describe_ring(java.lang.String keyspace)
                                             throws InvalidRequestException,
                                                    org.apache.thrift.TException

  get the token ring: a map of ranges to host addresses, represented as a set of TokenRange instead of a map from range to list of endpoints, because you can't use Thrift structs as map keys: https://issues.apache.org/jira/browse/THRIFT-162 for the same reason, we can't return a set here, even though order is neither important nor predictable.

  Parameters:
    `keyspace` -
  Throws:
    `InvalidRequestException`
    `org.apache.thrift.TException`

### describe_partitioner

                                          throws org.apache.thrift.TException

  returns the partitioner used by this cluster

  Throws:
    `org.apache.thrift.TException`

### describe_keyspace

    java.util.Map<java.lang.String,java.util.Map<java.lang.String,java.lang.String>> describe_keyspace(java.lang.String keyspace)
                                                                                                       throws NotFoundException,

  describe specified keyspace
