DynamoDB

Client

AsyncDynamoDBClient 

AsyncDynamoDBClient(config: AsyncDynamoDBConfig | None = None, plugins: list[Plugin] | None = None)

Amazon DynamoDB is a fully managed NoSQL database service that provides fast and predictable performance with seamless scalability. DynamoDB lets you offload the administrative burdens of operating and scaling a distributed database, so that you don't have to worry about hardware provisioning, setup and configuration, replication, software patching, or cluster scaling.

With DynamoDB, you can create database tables that can store and retrieve any amount of data, and serve any level of request traffic. You can scale up or scale down your tables' throughput capacity without downtime or performance degradation, and use the Amazon Web Services Management Console to monitor resource utilization and performance metrics.

DynamoDB automatically spreads the data and traffic for your tables over a sufficient number of servers to handle your throughput and storage requirements, while maintaining consistent and fast performance. All of your data is stored on solid state disks (SSDs) and automatically replicated across multiple Availability Zones in an Amazon Web Services Region, providing built-in high availability and data durability.

Parameters:

Name Type Description Default
config AsyncDynamoDBConfig | None

Optional configuration for the client. Here you can set things like the endpoint for HTTP services or auth credentials.

 None
plugins list[Plugin] | None

A list of callables applied once to the client's base configuration. Their changes are inherited by every operation invocation.

 None

A map of auth scheme ids to auth schemes.

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

The identifier for a secret access key.

aws_credentials_identity_resolver class-attribute instance-attribute 
aws_credentials_identity_resolver: IdentityResolver[AWSCredentialsIdentity, AWSIdentityProperties] | None = None

Resolves AWS Credentials. Required for operations that use Sigv4 Auth.

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

A secret access key that can be used to sign requests.

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

The session token used with temporary AWS credentials.

endpoint_resolver class-attribute instance-attribute 
endpoint_resolver: EndpointResolver | None = None

The endpoint resolver used to resolve the final endpoint per-operation based on the configuration.

interceptors class-attribute instance-attribute 
interceptors: list[_ServiceInterceptor] = field(default_factory=lambda: [])

The list of interceptors, which are hooks that are called during the execution of a request.

protocol class-attribute instance-attribute 
protocol: ClientProtocol[Any, Any] | None = None

The protocol to serialize and deserialize requests with.

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

The AWS region to connect to. The configured region is used to determine the service endpoint.

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

A unique and opaque application ID that is appended to the User-Agent header.

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

Additional suffix to be added to the User-Agent header.

Methods:

resolve async classmethod 
resolve(*, profile: str | None = None, fs: FileSystem | None = None, config_file_path: str | None = None, credentials_file_path: str | None = None, **overrides: Unpack[_AsyncDynamoDBConfigOverrides]) -> Self

Resolve config from environment, config files, defaults, and explicit overrides.

set_auth_scheme 
set_auth_scheme(scheme: AuthScheme[Any, Any, Any, Any]) -> None

Set an auth scheme implementation using its scheme ID. :param scheme: The auth scheme to add or replace.

Plugin module-attribute 

Plugin: TypeAlias = Callable[[AsyncDynamoDBConfig], None]

A callable that customizes a client configuration. Service-level plugins are applied once to the base configuration inherited by every operation. Operation-level plugins apply only to a single operation invocation.
