Hi there,

I'm currently learning about Logstash and am wondering if I can keep a "stateful" (let's just call it like that) object which I can use for enhancements.

E.g. a HTTP Request pushes a dictionary which is used as a lookup table for fields for incoming events from another input plugin.

Is this possible with Logstash? If so, I'd be happy to see an example!

Greetings,  
Matthias
