I have a logstash configuration. With that configuration logstash do some operation in filter and send outputs. Everything works well.
I want one more elasticsearch output in same configuration file. I mean after parsing the logs, logstash send results to one index after that removing some fields and send them to another index.
Note : I have also tried clone plugin but that is not solving the question cause this plugin use "type" keyword and i use this keyword in a lots place in my configuration.
My aim is in below example.
```auto
output {
elasticsearch {
..index1..
}
mutate {
remove_field ...
}
mutate {
add_field ..
}
elasticsearch {
... index2 ...
}
```
}
But i can not work with mutate plugin in output ? How can i achieve this ?
Thanks for answering

You can use pipeline-to-pipeline communication with a [forked-path](https://www.elastic.co/guide/en/logstash/current/pipeline-to-pipeline.html#forked-path-pattern) pattern.
