@Tags(value={"json","tree","record","reader","parser"}) @CapabilityDescription(value="Parses JSON into individual Record objects. The Record that is produced will contain all top-level elements of the corresponding JSON Object. The root JSON element can be either a single element or an array of JSON elements, and each element in that array will be treated as a separate record. If the schema that is configured contains a field that is not present in the JSON, a null value will be used. If the JSON contains a field that is not present in the schema, that field will be skipped.
