Suppose I have two tables like this in postgres:

User

- id
- name
- country\_id

Country

- id
- name

Now when I do:

```auto
jdbc {
    ...
    statement => "SELECT * FROM user JOIN country ON country.id = user.country_id"
}

```

I need data to be denormalized in elasticsearch like this:

```auto
{
  "name": "David",
  "country": {
     "name": "France"
  }
}

```

But it is coming out as flat.

Am I doing something wrong here? I followed [this](https://www.elastic.co/blog/logstash-jdbc-input-plugin) article.

This is expected. Logstash won't automatically create nested fields from the query results.
