We are trying to deploy logstash in production. So I need a detailed answer for these questions: -Logstash extracts data from database using SQL. How exactly logstash get notified about new data? -Is there a way to configure how logstash search new data? We cannot rely on this kind of abstraction (even if it maybe optimum) -is there any official performance reports that I can check? We are going to make our personal tests, but it’s still good to have a first impression. Thanks!! ---
