## Edn Codec configuration options


| Setting                                | Input type                                                    | Required |
|----------------------------------------|---------------------------------------------------------------|----------|
| [`target`](#plugins-codecs-edn-target) | [string](/docs/reference/logstash/plugins/value-types#string) | No       |


### `target`

- Value type is [string](/docs/reference/logstash/plugins/value-types#string)
- There is no default value for this setting.
- The option is only relevant while decoding.

Define the target field for placing the decoded fields. If this setting is not set, data will be stored at the root (top level) of the event.
For example, if you want data to be put under the `document` field:
```
    input {
      tcp {
        port => 4242
        codec => edn {
          target => "[document]"
        }
      }
    }
```
