title: How can I have events in aws lambda triggered regularly?
body: <p>SHORT VERSION: How can I trigger events regularly in AWS lambda?</p>
  
  <p>LONG VERSION: My situation is such that I have events in a database that expire within a certain time. I want to run a function (send push notifications, delete rows, etc.) whenever I figure out that an event has expired. I know that setting up a timer for every single event created would be impractical, but is there something that would scan my database every minute or something and look for expired events to run my code on? If not, is there some alternative for my solution? </p>
