Tagging Amazon Neptune resources

You can use Neptune tags to add metadata to your Neptune resources. In addition, you can use tags with Amazon Identity and Access Management (IAM) policies to manage access to Neptune resources and control what actions can be applied to those resources. Finally, you can use tags to track costs by grouping expenses for similarly tagged resources.

All Neptune administrative resources can be tagged, including the following:

  • DB instances

  • DB clusters

  • Read Replicas

  • DB snapshots

  • DB cluster snapshots

  • Event subscriptions

  • DB parameter groups

  • DB cluster parameter groups

  • DB subnet groups

Overview of Neptune resource tags

An Amazon Neptune tag is a name-value pair that you define and associate with a Neptune resource. The name is referred to as the key. Supplying a value for the key is optional. You can use tags to assign arbitrary information to a Neptune resource. You can use a tag key, for example, to define a category, and the tag value might be an item in that category. For example, you might define a tag key of “project” and a tag value of “Salix,” indicating that the Neptune resource is assigned to the Salix project. You can also use tags to designate Neptune resources as being used for test or production by using a key such as environment=test or environment=production. We recommend that you use a consistent set of tag keys to make it easier to track metadata that is associated with Neptune resources.

Use tags to organize your Amazon bill to reflect your own cost structure. To do this, sign up to get your Amazon Web Services account bill with tag key values included. Then, to see the cost of combined resources, organize your billing information according to resources with the same tag key values. For example, you can tag several resources with a specific application name, and then organize your billing information to see the total cost of that application across several services. For more information, see Using Cost Allocation Tags in the Amazon Billing User Guide.

Each Neptune resource has a tag set, which contains all the tags that are assigned to that Neptune resource. A tag set can contain as many as 10 tags, or it can be empty. If you add a tag to a Neptune resource that has the same key as an existing tag on resource, the new value overwrites the old value.

Amazon does not apply any semantic meaning to your tags; tags are interpreted strictly as character strings. Neptune can set tags on a DB instance or other Neptune resources, depending on the settings that you use when you create the resource. For example, Neptune might add a tag indicating that a DB instance is for production or for testing.

  • The tag key is the required name of the tag. The string value can be from 1 to 128 Unicode characters in length and cannot be prefixed with "aws:" or "rds:". The string can contain only the set of Unicode letters, digits, white space, '_', '.', '/', '=', '+', '-' (Java regex: "^([\\p{L}\\p{Z}\\p{N}_.:/=+\\-]*)$").

  • The tag value is an optional string value of the tag. The string value can be from 1 to 256 Unicode characters in length and cannot be prefixed with "aws:". The string can contain only the set of Unicode letters, digits, white space, '_', '.', '/', '=', '+', '-' (Java regex: "^([\\p{L}\\p{Z}\\p{N}_.:/=+\\-]*)$").

    Values do not have to be unique in a tag set and can be null. For example, you can have a key-value pair in a tag set of project/Trinity and cost-center/Trinity.

Note

You can add a tag to a snapshot. However, your bill won't reflect this grouping.

You can use the Amazon Web Services Management Console, the Amazon CLI, or the Neptune API to add, list, and delete tags on Neptune resources. When using the Amazon CLI or the Neptune API, you must provide the Amazon Resource Name (ARN) for the Neptune resource that you want to work with. For more information about constructing an ARN, see Constructing an ARN for Neptune.

Tags are cached for authorization purposes. Because of this, additions and updates to tags on Neptune resources can take several minutes before they are available.
