[jira] [Created] (SPARK-29440) Support java.time.Duration as an external type of CalendarIntervalType

Maxim Gekk created SPARK-29440:
----------------------------------

             Summary: Support java.time.Duration as an external type of CalendarIntervalType
                 Key: SPARK-29440
                 URL: https://issues.apache.org/jira/browse/SPARK-29440
             Project: Spark
          Issue Type: Improvement
          Components: SQL
    Affects Versions: 2.4.4
            Reporter: Maxim Gekk


Currently, Spark SQL doesn't have any external type for Catalyst's CalendarIntervalType. Internal CalendarInterval is partially exposed but it cannot be used in UDF for example. This ticket aims to provide `java.time.Duration` as one of external types of Spark `INTERVAL`.
