Hi all,  
i have question regarding to logstash architecture,  
i will use twitter-input-plugin to scrape some tweets in real-time.  
When I get tweet from logstash-twitter-input i need to call 2 web-services to get additional field to tweet.  
From logstash point of view (performance) is better to customize logstash-input-plugin (and call web-services from input plugin layer) or develop custom filter plugin which will add these additional fields?  
Thanks at all  
Ondrej
