MaxGekk commented on issue #27836: [SPARK-31009][SQL] Support json_object_keys function URL: https://github.com/apache/spark/pull/27836#issuecomment-595860127 We can get the same result using existing functions: ```scala scala> val df = Seq("""{"a":1, "b":2}""").toDF("json") df: org.apache.spark.sql.DataFrame = [json: string] scala> df.select(map_keys(from_json($"json", MapType(StringType, StringType)))).show +-----------------+ |map_keys(entries)| +-----------------+ | [a, b]| +-----------------+ ``` What's the benefit of having the function in public API?
