S3 Event NotificationsΒΆ

  • S3:ObjectCreated, S3:ObjectRemoved, S3:ObjectRestore, S3:Replication
  • Object name filtering possible (*.jpg)
  • Use case: generate thumbnails of images uploaded to S3

  • Can create as many "S3 events" as desired

  • S3 event notifications typically deliver events in seconds but can sometimes take a minute or longer

  • If two writes are made to a single non-versioned object at the same time, it is possible that only a single event notification will be sent.
  • If you want to ensure that an event notification is sent for every sucessful write, you can enable versioning in your bucket.
