> Improve TimestampNTZ support in JDBC data source
> ------------------------------------------------
>
> Key: SPARK-43040
> URL: https://issues.apache.org/jira/browse/SPARK-43040
> Project: Spark
> Issue Type: Improvement
> Components: SQL
> Affects Versions: 3.3.3, 3.4.0
> Reporter: Tianhan Hu
> Assignee: Tianhan Hu
> Priority: Major
>
> [https://github.com/apache/spark/pull/36726] supports TimestampNTZ type in
> JDBC data source and [https://github.com/apache/spark/pull/37013] applies a
> fix to pass more test cases with H2.
> The problem is that Java Timestamp is a poorly defined class and different
> JDBC drivers implement "getTimestamp" and "setTimestamp" with different
> expected behaviors in mind. The general conversion implementation would work
> with some JDBC dialects and their drivers but not others. This issue is
> discovered when testing with PostgreSQL database.
> We will need to have dialect specific conversions between JDBC timestamps and
> TimestampNTZ.
