@Christian_Dahlqvist I see what your saying, so basically in order to detect a duplicate in logstash properly you'd have to create some kind of duplicate service and find a way to scale it which adds more complexity. Hmm. Ok, so as you said if Elasticsearch can handle it, basically a feature in elasticsearch to drop it would be more efficient. I will move my feature request from logstash to elasticsearch.

Thanks,
