I have an ELK infrastructure that has

- 1 Kibana/Logstash node
- 1 Elasticsearch client node
- 3 Elasticsearch master nodes
- 2 Elasticsearch data nodes

On my Logstash's output filter, which node should I point my Logstash elasticsearch filter to, the client node, or the data nodes? IOW

This?

```
output {
  elasticsearch {
    hosts => ["https://elk-CLIENT:9200"]
  }
}

```

or this?

```
output {
  elasticsearch {
    hosts => ["https://elk-DATA-0:9200", "https://elk-DATA-1:9200"]
  }
}
```
