> Key: SPARK-13185
> URL: https://issues.apache.org/jira/browse/SPARK-13185
> Project: Spark
> Issue Type: Improvement
> Components: SQL
> Affects Versions: 1.6.0
> Reporter: Carson Wang
> Priority: Minor
>
> It is expensive to create java TimeZone and Calendar objects in each method
> of DateTimeUtils. We can reuse the objects to improve the performance. In one
> of my Sql queries which calls StringToDate many times, the duration of the
> stage improved from 1.6 minutes to 1.2 minutes.
