I have a column family for sorting time-uuid and expect to retrieve columns in descending order (i.e. latest on the top). but the following get_slice call returns column in ascending order.  Does cassandra sort time-uuid column in descending order by default? Should get_slice call return the most recent time-uuid?

    <ColumnFamily CompareWith="TimeUUIDType" Name="Index"/>

    ColumnParent columnParent = new ColumnParent(cf);
    SlicePredicate predicate = new SlicePredicate();
    SliceRange sliceRange = new SliceRange();
    sliceRange.setStart(new byte[] {});
    sliceRange.setFinish(new byte[] {});
    return client.get_slice(keyspace, key, columnParent, predicate, ConsistencyLevel.ONE);
