What are S3 Event Notifications?

Amazon S3 Event Notifications allow you to receive notifications when specific events occur in your S3 buckets. These notifications can be sent to various destinations, such as AWS Lambda functions, Amazon Simple Notification Service (SNS), Amazon Simple Queue Service (SQS), and more. With S3 Event Notifications, you can respond to changes in your data without having to continuously poll for updates.
