Hi,

I want to create a plugin (or something similar) that inspects the data sent from logstash before it is inserted in elastic.  
I found this documentation: [https://www.elastic.co/guide/en/elasticsearch/reference/current/modules-scripting.html#native-java-scripts](https://www.elastic.co/guide/en/elasticsearch/reference/current/modules-scripting.html#native-java-scripts)

But how can I tell elastic that my code should be called before the insert occurs?  
Is a plugin the correct way?

Take a look at ingest nodes. They are being developed right now, and will allows this exact functionality:
