Subject [jira] [Created] (SPARK-30324) Simplify API for JSON access in DataFrames/SQL
Date Fri, 20 Dec 2019 19:08:00 GMT
Burak Yavuz created SPARK-30324:
-----------------------------------

             Summary: 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


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 asĀ get_json_object.

This nested access can then be extended in the future to other semi-structured formats.
