json_array_elements and json_build_object in Datafusion?

[dadepo]

From looking around the documentation, it looks like Datafusion does not natively have any functionality comparable to json_array_elements and json_build_object?

json_array_elements for allows arrays to be treated as rows
json_build_object for constructing json object from column values

See postgresql documentation for reference https://www.postgresql.org/docs/current/functions-json.html

Is this the case? or there are ways to kinda achieve the same thing natively in Datafusion?
