> Read and write CalendarIntervals using one call to get/putLong consistently
> ---------------------------------------------------------------------------
>
> Key: SPARK-51042
> URL: https://issues.apache.org/jira/browse/SPARK-51042
> Project: Spark
> Issue Type: Bug
> Components: SQL
> Affects Versions: 4.0.0, 3.5.4, 3.5.5, 4.1.0
> Reporter: Jonathan Albrecht
> Assignee: Jonathan Albrecht
> Priority: Minor
> Labels: big-endian, pull-request-available
> Fix For: 4.0.0, 3.5.5
>
>
> In commit ac07cea234f4fb687442aafa8b6d411695110a4e there was a performance
> improvement to reading a writing CalendarIntervals in UnsafeRow. This same
> change can be applied to UnsafeArrayData and UnsafeWriter.
> This would also fix big endian platforms where the current and proposed
> methods of reading and writing CalendarIntervals do not order the bytes in
> the same way. Currently CalendarInterval related tests in Catalyst and SQL
> are failing on big endian platforms.
> There would be no effect on little endian platforms (byte order is not
> affected) except for performance improvement.
