Use a split filter

```
    mutate { remove_field => ["messages"] }
    split { field => "datapoints" }

```

You can move the fields to the root level using [How to dynamically move nested key value to root level](https://discuss.elastic.co/t/how-to-dynamically-move-nested-key-value-to-root-level/180006/2).
