Dongjoon Hyun updated SPARK-30324:
----------------------------------
Target Version/s: 3.1.0
> Simplify API for JSON access in DataFrames/SQL
> ----------------------------------------------
>
> Key: SPARK-30324
> URL: https://issues.apache.org/jira/browse/SPARK-30324
> Project: Spark
> Issue Type: New Feature
> Components: SQL
> Affects Versions: 2.4.4
> Reporter: Burak Yavuz
> Priority: Major
>
> get_json_object() is a UDF to parse JSON fields. It is verbose and hard to
> use, e.g. I wasn't expecting the path to a field to have to start with "$.".
> We can simplify all of this when a column is of StringType, and a nested
> field is requested. This API sugar will in the query planner be rewritten as
> get_json_object.
> This nested access can then be extended in the future to other
> semi-structured formats.
