MaxGekk commented on issue #26134: [SPARK-29486][SQL] CalendarInterval should have 3 fields: months, days and microseconds URL: https://github.com/apache/spark/pull/26134#issuecomment-543060770 > My PR change current behavior but it gives the user a choice to use a physical 1 day (23,24,25 hours maybe) or use a logical 1 day (24 hours exactly, this is consistent to current behavior). This change can reduce the ambiguity. I agree. > CalendarInterval usually is a constant value and used to shift a column of timestamp type. This means we rarely save CalendarInterval as a column of a table. @LinhongLiu Recently, we supported subtractions of timestamps and dates, see #26022, #26036, and #26112. I expect more columns of the `INTERVAL` type in users tables in the future.
