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-534520091 > What do you mean by "already exposed"? CalendarInterval is the internal data representation of interval type, like long for timestamp type and int for date type. I mean when an user collects an interval column, she/he gets `CalendarInterval`: ``` scala> spark.sql("select interval '10' year").collect()(0).get(0).isInstanceOf[org.apache.spark.unsafe.types.CalendarInterval] res9: Boolean = true ```
