> This is a follow-up task of IMPALA-376 where we implemented the built-in function as Hive's get_json_object.
> In ANSI SQL standard, there're other JSON functions to support:
> * {{json_exists(<json>, <path>)}}
> * {{json_value(<json>, <path> [returning <type>])}}
> * {{json_query(<json>, <path> …)}}{{}}
