If you have neither a sequence nor a timestamp in your data then I don't think you can unless your database supports triggers when new values are added. But that's really a database question and not a logstash question.

That is very much specific to the database that you are using. In general, a trigger is a PL/SQL function that is called when a row is modified in a table. That function could execute an HTTP POST into a logstash http input (there are several other options for which input to use). I cannot give you more than a 30,000 foot overview.
