title: Get alerts from MySQL to Jenkins when specific data changes
body: <p>I have an interesting challenge I am trying to solve.
  Say you have a table on MySQL you'd like to know was changed. 
  I want to receive an alert of some kind to Jenkins with the details of the change.
  At the moment, there's a script that polls the DB and checks wether there was a change. This seems like a not optimal solution. Is there a better way to implement this? Preferably without installing additional software?
  Thanks!</p>
