put_resource_policy

Operation

put_resource_policy async

put_resource_policy(input: PutResourcePolicyInput, plugins: list[Plugin] | None = None) -> PutResourcePolicyOutput

Attaches a resource-based policy document to the resource, which can be a table or stream. When you attach a resource-based policy using this API, the policy application is eventually consistent .

PutResourcePolicy is an idempotent operation; running it multiple times on the same resource using the same policy document will return the same revision ID. If you specify an ExpectedRevisionId that doesn't match the current policy's RevisionId, the PolicyNotFoundException will be returned.

Note

PutResourcePolicy is an asynchronous operation. If you issue a GetResourcePolicy request immediately after a PutResourcePolicy request, DynamoDB might return your previous policy, if there was one, or return the PolicyNotFoundException. This is because GetResourcePolicy uses an eventually consistent query, and the metadata for your policy or table might not be available at that moment. Wait for a few seconds, and then try the GetResourcePolicy request again.

Parameters:

Name Type Description Default
input PutResourcePolicyInput

An instance of PutResourcePolicyInput.

required
plugins list[Plugin] | None

A list of callables that modify the configuration dynamically. Changes made by these plugins only apply for the duration of the operation execution and will not affect any other operation invocations.

None

Returns:

Type Description
PutResourcePolicyOutput

An instance of PutResourcePolicyOutput.

Input

PutResourcePolicyInput dataclass

Dataclass for PutResourcePolicyInput structure.

Attributes

confirm_remove_self_resource_access class-attribute instance-attribute
confirm_remove_self_resource_access: bool = False

Set this parameter to true to confirm that you want to remove your permissions to change the policy of this resource in the future.

expected_revision_id class-attribute instance-attribute
expected_revision_id: str | None = None

A string value that you can use to conditionally update your policy. You can provide the revision ID of your existing policy to make mutating requests against that policy.

Note

When you provide an expected revision ID, if the revision ID of the existing policy on the resource doesn't match or if there's no policy attached to the resource, your request will be rejected with a PolicyNotFoundException.

To conditionally attach a policy when no policy exists for the resource, specify NO_POLICY for the revision ID.

policy class-attribute instance-attribute
policy: str | None = None

An Amazon Web Services resource-based policy document in JSON format.

  • The maximum size supported for a resource-based policy document is 20 KB. DynamoDB counts whitespaces when calculating the size of a policy against this limit.

  • Within a resource-based policy, if the action for a DynamoDB service-linked role (SLR) to replicate data for a global table is denied, adding or deleting a replica will fail with an error.

For a full list of all considerations that apply while attaching a resource-based policy, see Resource-based policy considerations.

resource_arn class-attribute instance-attribute
resource_arn: str | None = None

The Amazon Resource Name (ARN) of the DynamoDB resource to which the policy will be attached. The resources you can specify include tables and streams.

You can control index permissions using the base table's policy. To specify the same permission level for your table and its indexes, you can provide both the table and index Amazon Resource Name (ARN)s in the Resource field of a given Statement in your policy document. Alternatively, to specify different permissions for your table, indexes, or both, you can define multiple Statement fields in your policy document.

Output

PutResourcePolicyOutput dataclass

Dataclass for PutResourcePolicyOutput structure.

Attributes

revision_id class-attribute instance-attribute
revision_id: str | None = None

A unique string that represents the revision ID of the policy. If you're comparing revision IDs, make sure to always use string comparison logic.
