How does eXtremeDB optimize for time series?

Question

I'm trying to understand how eXtremeDB optimizes for time series. The official documentation mentions the use of the SEQUENCE data type. When defining a column of this type, one is also required to declare the scalar_data_type and specify either ASC or DESC. However, the documentation leaves several questions unanswered:

1. What data types are included under scalar_data_type?
2. Does ASC/DESC imply that the data is sorted according to its value?

Lastly, is the SEQUENCE data type in eXtremeDB supposed to optimize time series management?

Any insights would be appreciated!
