      provider: Amazon DynamoDB
      first-party-contract: smithy/dynamodb-2012-08-10.json (github.com/aws/api-models-aws, Smithy 2.0,
        58 operations)
      coverage-note: This document covers 5 of the 58 operations AWS models. It is an API Evangelist rendering
        of the AWS API Reference, not an AWS-published OpenAPI - AWS publishes Smithy, not OpenAPI.
