             Summary: Performance improvement while converting stringToTimestamp in DateTimeUtils
                 Key: SPARK-24457
                 URL: https://issues.apache.org/jira/browse/SPARK-24457
             Project: Spark
          Issue Type: Improvement
          Components: SQL
    Affects Versions: 2.3.0
            Reporter: Sharad Sonker


stringToTimestamp in DateTimeUtils creates Calendar instance for each input row even if the input timezone is same. This can be improved by caching the calendar instance for each input timezone.
