is there a possibility to update a document if id matches else insert ?  
Alright i'm reading a kafka topic and this a sample of my topic

`

`> "schema":{"type":"struct","fields":[{"type":"string","optional":true,"field":"name"},{"type":"string","optional":true,"field":"season"},{"type":"string","optional":true,"field":"id"}],"optional":false,"name":"mongo_conn.test.testCollection"},"payload":{"name":"aothertest","season":"reallyweird","id":"5d0a2a75baff7c1e89ef44d3"}}`

`

ps: all i need is found under payload [name,season,id]

and this is my logstash input

> ```
> input {
> kafka {
> bootstrap_servers => "localhost:9092"
> topics => "mongo_conn.test.testCollection"
> auto_offset_reset => "earliest"
> codec => json{}
> }
> }
> 
> ```

for example incase if payload.id matches a already existing payload.id , update the document

If you are using an elasticsearch output then you can use [doc\_as\_upsert](https://www.elastic.co/guide/en/logstash/current/plugins-outputs-elasticsearch.html#plugins-outputs-elasticsearch-doc_as_upsert).

@Badger I've added that, but nothing happens it keeps on pushing the update as a new insert maybe i need to specify the id nested in payload ? as i mentioned before all my info are inside payload the rest i don't need it's just the way the format is in kafka

You are using

```
document_id => "%{[payload][id]}"

```

right?

I believe if you are setting doc\_as\_upsert then you should be using action =\> "update".
