I'm using `jdbc-input-plugin` to get some orders data and send it to a `rabbitmq` queue.

To make the json message compatible with the queue consuming system, I need to add a root named `order`.

I'm getting

```auto
{ "id" : 123, "price" : 12.50 }

```

and I need it to be

```auto
{ "order" : { "id" : 123, "price" : 12.50 } }

```

Is there any way I can inform the `jdbc-input` to use `order` as the default root for the message ?

I know I can achieve this with mutate filter like :

```auto
filter {
  mutate {
    add_field => {
      "[order][id]" => "%{[id]}"
      "[order][price]" => "%{[price]}"
    }

    remove_field => ["id", "price"]
  }
}

```

But I hope there's a better way 😉

No other way that I know of.

FYI. You can use `add_field` on the jdbc\_input - it will run that function after the event is created.  
If you have any other filter, just add the `remove_field` piece in it before the event hits the output section.
