Apache Spark reassigned SPARK-36346:
------------------------------------
Assignee: (was: Apache Spark)
> Support TimestampNTZ type in Orc file source
> --------------------------------------------
>
> Key: SPARK-36346
> URL: https://issues.apache.org/jira/browse/SPARK-36346
> Project: Spark
> Issue Type: Sub-task
> Components: SQL
> Affects Versions: 3.3.0
> Reporter: jiaan.geng
> Priority: Major
>
> As per https://orc.apache.org/docs/types.html, Orc supports both
> TIMESTAMP_NTZ and TIMESTAMP_LTZ (Spark's current default timestamp type):
> * A TIMESTAMP => TIMESTAMP_LTZ
> * Timestamp with local time zone => TIMESTAMP_NTZ
> In Spark 3.1 or prior, Spark only considered TIMESTAMP.
> Since 3.2, with the support of timestamp without time zone type:
> * Orc writer follows the definition and uses "Timestamp with local time zone"
> on writing TIMESTAMP_NTZ.
> * Orc reader converts the "Timestamp with local time zone" to TIMESTAMP_NTZ.
