3/// Configuration for a aws_sdk_dynamodb service client.
4///
5///
6/// Service configuration allows for customization of endpoints, region, credentials providers,
7/// and retry configuration. Generally, it is constructed automatically for you from a shared
8/// configuration loaded by the `aws-config` crate. For example:
9///
10/// ```ignore
11/// // Load a shared config from the environment
12/// let shared_config = aws_config::from_env().load().await;
13/// // The client constructor automatically converts the shared config into the service config
14/// let client = Client::new(&shared_config);
15/// ```
16///
17/// The service config can also be constructed manually using its builder.
18///
