title: Trigger Aws Lambda when a folder is uploaded on s3 console
body: <p>How can we trigger aws lambda only when the folder is uploaded having prefix configurations set as another folder.</p>
  
  <p>for eg. we have images/ folder inside bucket. And now we want to trigger when a date folder i.e. 20181128 is uploaded to images folder, having images inside in it.</p>
  
  <p>individual images shouldn't trigger lambda, rather only uploaded folder should trigger.</p>
  
  <p>What s3 trigger configuration should be set in this condition? </p>
  
  <p>I have gone through lot of scenarios and individual images is triggering lambda, which I don't want.
  I want it should trigger only when a folder is uploaded.</p>
