What Is It?

Batch Operations lets you perform the same action on thousands or millions of S3 objects in a single job — instead of doing it one file at a time.

What You Can Do With It

• Modify object metadata and properties
• Copy objects between S3 buckets
• Encrypt objects that are currently unencrypted
• Modify ACLs and tags
• Restore objects from S3 Glacier
• Invoke a Lambda function to run custom code on each object

How it works - The Flow

A job consists of three things: a list of objects, the action to perform, and any optional parameters.

Step 1: S3 Inventory
↓ (creates a list of all your files)

Step 2: Athena (optional)
↓ (filter the list - only process .jpg files, for example)

Step 3: User picks operation
↓ (what do you want to do?)

Step 4: S3 Batch Operations runs
↓ (processes all files automatically)

Step 5: Done!
- You get reports
- You get notifications when complete

What S3 Batch Operations Manages for You

• Automatic retries on failures
• Progress tracking
• Completion notifications
• Report generation when the job finishes

You do not need to write any scripts or manage errors yourself.
