BytesType sorts values in byte order. That is: "2" (byte 50) is bigger than "10" (byte 49 48). It may or may not be relevant to your problem, depending on your column names and the inputs.

So, let's suppose I have two columns: 1, 3. If I insert column 2 I will end up with 1, 2, 3, ok? I'm using the default BytesType as the Comparator type to store time series columns (actually the value is a C# DateTime.Ticks value - a long int). The columns aren't inserted in order. But, later, when I use get_slice with something like: slice.Slice_range.Start = BitConverter.GetBytes(dateFrom.Value.Ticks); slice.Slice_range.Finish = BitConverter.GetBytes(dateTo.Value.Ticks); where dateFrom and dateTo are supplied by the user and may not (most likely) correspond to an existing column name. I'm getting some really weird results, from dates that are even outside the range supplied. Any hint about this? /Gustavo
