> -------------------------------
>
> Key: SPARK-27790
> URL: https://issues.apache.org/jira/browse/SPARK-27790
> Project: Spark
> Issue Type: New Feature
> Components: SQL
> Affects Versions: 3.2.0
> Reporter: Maxim Gekk
> Assignee: Apache Spark
> Priority: Major
>
> SQL standard defines 2 interval types:
> # year-month interval contains a YEAR field or a MONTH field or both
> # day-time interval contains DAY, HOUR, MINUTE, and SECOND (possibly fraction
> of seconds)
> Need to add 2 new internal types YearMonthIntervalType and
> DayTimeIntervalType, support operations defined by SQL standard as well as
> INTERVAL literals.
> The java.time.Period and java.time.Duration can be supported as external type
> for YearMonthIntervalType and DayTimeIntervalType.
