title: Can I execute any program outside mysql through mysql triggers?
body: <p>I’m building email notification service, requirement is to send an email to user when he is registered.
  Currently what I’m thinking of execution of some function defined in trigger, can be a java function, which have to be outside the mysql process, rather monitoring mysql from outside for row addition in database.</p>
  
  <p>Is there any functionality available in mysql, so that I can execute my java function from database triggers?</p>
