> Format Java date-time types in Row.jsonValue directly
> -----------------------------------------------------
>
> Key: SPARK-31802
> URL: https://issues.apache.org/jira/browse/SPARK-31802
> Project: Spark
> Issue Type: Sub-task
> Components: SQL
> Affects Versions: 3.0.0, 3.1.0
> Reporter: Maxim Gekk
> Assignee: Maxim Gekk
> Priority: Major
> Fix For: 3.0.0
>
>
> Row.jsonValue has to convert incoming Java date/timestamps types to
> days/microseconds because DateFormatter/TimestampFormatter APIs didn't
> accept java.sql.Timestamp/java.util.Date and
> java.time.Instant/java.time.LocalDate before
> https://issues.apache.org/jira/browse/SPARK-31762. Internally, the formatters
> perform conversions to Java types again. This badly impacts on the
> performance. The ticket aims to add new APIs to DateFormatter and
> TimestampFormatter that should accept Java types.
