----------------------------------
Resolution: Duplicate
> Infer date type for Json schema inference
> -----------------------------------------
>
> Key: SPARK-40649
> URL: https://issues.apache.org/jira/browse/SPARK-40649
> Project: Spark
> Issue Type: Improvement
> Components: SQL
> Affects Versions: 3.2.1
> Reporter: Xiaonan Yang
> Assignee: Jonathan Cui
> Priority: Major
> Fix For: 3.4.0
>
>
> 1. If a column contains only dates, it should be of “date” type in the
> inferred schema
> * If the date format and the timestamp format are identical (e.g. both are
> yyyy/mm/dd), entries will default to being interpreted as Date
> 2. If a column contains dates and timestamps, it should be of “timestamp”
> type in the inferred schema
>
> A similar issue was opened in the past but was reverted due to the lack of
> strict pattern matching.
