Other AWS S3 Features

S3 Batch

S3 Batch is an AWS-managed feature that allows us to manage billions of S3 objects in a bucket in a single S3 Batch Operation. S3 Batch actions include:

• To copy all selected objects to a destination.
• Invoke AWS Lambda functions on the specified objects.
• Replicate all selected objects to a destination.
• Replace all object tags on specified objects.
• Delete all object tags on specified objects.
• Replace ACL for every object.
• Set object lock feature on S3 objects, i.e., Object Lock retention
• The object Lock legal hold, which prevents objects from being deleted or overwritten until the legal hold is removed.

• The S3 Batch service needs an IAM role with appropriate permissions to do its tasks.
• It keeps track of failures and generates a report on task completion.
• We can use S3 Inventory to get the S3 object list and information and S3 Select to filter the list.
