IAM permissions

If you want to set up a separate IAM user for Dynamic DynamoDB, then you need to grant the user the following privileges:

  • cloudwatch:GetMetricStatistics
  • dynamodb:DescribeTable
  • dynamodb:ListTables
  • dynamodb:UpdateTable
  • sns:Publish (used by the SNS notifications feature)

Example IAM policy

Here's an example IAM policy. Please make sure you update the ARNs according to your needs.

{
  "Version": "2012-10-17",
  "Statement": [
    {
      "Effect": "Allow",
      "Action": [
        "dynamodb:DescribeTable",
        "dynamodb:ListTables",
        "dynamodb:UpdateTable",
        "cloudwatch:GetMetricStatistics"
      ],
      "Resource": [
        "*"
      ]
    },
    {
      "Effect": "Allow",
      "Action": [
        "sns:Publish"
      ],
      "Resource": [
        "arn:aws:sns:*::dynamic-dynamodb"
      ]
    }
  ]
}
