MaxGekk commented on issue #25022: [SPARK-24695][SQL] Move `CalendarInterval` to org.apache.spark.sql.types package URL: https://github.com/apache/spark/pull/25022#issuecomment-534214406 @cloud-fan I would consider only 2 options: - Keep as is, and expose existing `CalendarInterval` in UDF, or - Follow SQL standard, and expose 2 types from Java standard library - `Period` and `Duration`. It seems nobody here likes the second option. So, I would do the first one instead of changing semantic of already exposed `CalendarInterval` in any ways.
