Hi Team,

Im adding the fingerprint of method UUID to avoid the duplication of the data.  
Im using kafka as producer and Elasticsearch as consumer.

Example pipeline conf looks like this

```auto
input
{
        kafka
         {
                bootstrap_servers => ["xxxxxxx:9093"]
                topics => ["xxxxxx"]
               ......
               .......
        }
}

filter {
  fingerprint {
    target => "generated_id"
    method => "UUID"
  }
}

output {
      elasticsearch {
                hosts => ["https://xxxxxxxxxx:9200"]
                document_id => "%{[generated_id]}"

```

Using this method we are not able to achieve the deduplication of data on the Elasticsearch side.

Can we solve this problem using any other approach?

Yes, use a fingerprint filter but do not use UUID. See the [documentation](https://www.elastic.co/guide/en/logstash/current/plugins-filters-fingerprint.html#_description_137):

> When the `method` option is set to `UUID` the result won’t be a consistent hash but a random [UUID](https://en.wikipedia.org/wiki/Universally_unique_identifier)
