 The `decode_json_fields` processor has the following configuration settings:
 
 `fields`:: The fields containing JSON strings to decode.
-`process_array`:: (Optional) A boolean that specifies whether to process
-arrays. The default is false.
-`max_depth`:: (Optional) The maximum parsing depth. A value of 1 will decode the
-JSON objects in fields indicated in `fields`, a value of 2 will also decode the
-objects embedded in the fields of these parsed documents. The default is 1.

 read. To merge the decoded JSON fields into the root of the event, specify
 `target` with an empty string (`target: ""`). Note that the `null` value (`target:`)

-`overwrite_keys`:: (Optional) A boolean that specifies whether keys that already
