--------------------------------
Summary: Support recursive descent path in get_json_object function
Key: SPARK-47992
URL: https://issues.apache.org/jira/browse/SPARK-47992
Project: Spark
Issue Type: New Feature
Components: SQL
Affects Versions: 4.0.0
Reporter: Qian Sun
JSONPath borrows recursive descent syntax from E4X. We could use it to collect
json object from json map string.
{code:java}
// json data
{"key1": {"b": {"c": "c1", "d": "d1", "e": "e1"}}}
{"key2": {"b": {"c": "c2", "d": "d2", "e": "e2"}}}
select get_json_object(data, '$..c'); -- [c1, c2]{code}
