      Truncates (deletes) the given columnFamily from the provided keyspace. Calling truncate results in actual deletion of all data in the cluster under the given columnFamily and it will fail unless all hosts are up. All data in the given column family will be deleted, but its definition will not be affected.
      Parameters:
        `keyspace` - The keyspace to delete from
        `columnFamily` - The column family to delete data from.
      Throws:
        `java.util.concurrent.TimeoutException`
        `java.io.IOException`

    - #### getOwnership

          java.util.Map<java.net.InetAddress,java.lang.Float> getOwnership()

      Effective ownership is % of the data each node owns given the keyspace we calculate the percentage using replication factor. If Keyspace == null, this method will try to verify if all the keyspaces in the cluster have the same replication strategies and if yes then we will use the first else a empty Map is returned.
