Controlling access and labeling jobs using tags

You can label and control access to your S3 Batch Operations jobs by adding tags. Tags can be used to identify who is responsible for a Batch Operations job. The presence of job tags can grant or limit a user's ability to cancel a job, activate a job in the confirmation state, or change a job's priority level. You can create jobs with tags attached to them, and you can add tags to jobs after they are created. Each tag is a key-value pair that can be included when you create the job or updated later.

Warning

Job tags should not contain any confidential information or personal data.

Consider the following tagging example: Suppose that you want your Finance department to create a Batch Operations job. You could write an Amazon Identity and Access Management (IAM) policy that allows a user to invoke CreateJob, provided that the job is created with the Department tag assigned the value Finance. Furthermore, you could attach that policy to all users who are members of the Finance department.

Continuing with this example, you could write a policy that allows a user to update the priority of any job that has the desired tags, or cancel any job that has those tags. For more information, see Controlling permissions for S3 Batch Operations using job tags.

You can add tags to new S3 Batch Operations jobs when you create them, or you can add them to existing jobs.

Note the following tag restrictions:

  • You can associate up to 50 tags with a job as long as they have unique tag keys.

  • A tag key can be up to 128 Unicode characters in length, and tag values can be up to 256 Unicode characters in length.

  • The key and values are case sensitive.

For more information about tag restrictions, see User-Defined Tag Restrictions in the Amazon Billing and Cost Management User Guide.

API operations related to S3 Batch Operations job tagging

Amazon S3 supports the following API operations that are specific to S3 Batch Operations job tagging:

  • GetJobTagging — Returns the tag set associated with a Batch Operations job.

  • PutJobTagging — Replaces the tag set associated with a job. There are two distinct scenarios for S3 Batch Operations job tag management using this API action:

    • Job has no tags — You can add a set of tags to a job (the job has no prior tags).

    • Job has a set of existing tags — To modify the existing tag set, you can either replace the existing tag set entirely, or make changes within the existing tag set by retrieving the existing tag set using GetJobTagging, modify that tag set, and use this API action to replace the tag set with the one you have modified.

      Note

      If you send this request with an empty tag set, S3 Batch Operations deletes the existing tag set on the object. If you use this method, you are charged for a Tier 1 Request (PUT). For more information, see Amazon S3 pricing.

      To delete existing tags for your Batch Operations job, the DeleteJobTagging action is preferred because it achieves the same result without incurring charges.

  • DeleteJobTagging — Deletes the tag set associated with a Batch Operations job.
