IAM policy to grant access to search a vector index - Amazon DynamoDB

IAM policy to grant access to search a vector index

The following policy grants permissions to perform SearchVectors operations on a specific vector index. The resource ARN for a vector index uses the same format as other DynamoDB indexes.

{
    "Version": "2012-10-17",
    "Statement": [
        {
            "Effect": "Allow",
            "Action": "dynamodb:SearchVectors",
            "Resource": "arn:aws:dynamodb:us-west-2:123456789012:table/Products/index/ProductEmbeddingIndex"
        }
    ]
}

To grant SearchVectors access to all indexes on a table, use a wildcard character (*) for the index name.

"Resource": "arn:aws:dynamodb:us-west-2:123456789012:table/Products/index/*"
No additional permissions required

No additional IAM permissions are required to create or delete vector indexes. The existing dynamodb:CreateTable and dynamodb:UpdateTable permissions are sufficient.

FGAC condition keys not supported for SearchVectors

Fine-grained access control (FGAC) condition keys are not supported for the SearchVectors API. You cannot use dynamodb:LeadingKeys, dynamodb:Attributes, or dynamodb:Select condition keys to restrict SearchVectors access.
