Overview

Package qldbsession provides the API client, operations, and parameter types for Amazon QLDB Session.

The transactional data APIs for Amazon QLDB

Instead of interacting directly with this API, we recommend using the QLDB driver or the QLDB shell to execute data transactions on a ledger.

  • If you are working with an AWS SDK, use the QLDB driver. The driver provides a high-level abstraction layer above this QLDB Session data plane and manages SendCommand API calls for you. For information and a list of supported programming languages, see Getting started with the driverin the Amazon QLDB Developer Guide.

  • If you are working with the AWS Command Line Interface (AWS CLI), use the QLDB shell. The shell is a command line interface that uses the QLDB driver to interact with a ledger. For information, see Accessing Amazon QLDB using the QLDB shell.

Functions

func NewDefaultEndpointResolver 

func NewDefaultEndpointResolver() *internalendpoints.Resolver

NewDefaultEndpointResolver constructs a new service endpoint resolver

func WithAPIOptions 

func WithAPIOptions(optFns ...func(*middleware.Stack) error) func(*Options)

WithAPIOptions returns a functional option for setting the Client's APIOptions option.

func WithEndpointResolver deprecated 

func WithEndpointResolver(v EndpointResolver) func(*Options)

Deprecated: EndpointResolver and WithEndpointResolver. Providing a value for this field will likely prevent you from using any endpoint-related service features released after the introduction of EndpointResolverV2 and BaseEndpoint.

To migrate an EndpointResolver implementation that uses a custom endpoint, set the client option BaseEndpoint instead.

func WithEndpointResolverV2 

func WithEndpointResolverV2(v EndpointResolverV2) func(*Options)

WithEndpointResolverV2 returns a functional option for setting the Client's EndpointResolverV2 option.

func WithSigV4SigningName 

func WithSigV4SigningName(name string) func(*Options)

WithSigV4SigningName applies an override to the authentication workflow to use the given signing name for SigV4-authenticated operations.

This is an advanced setting. The value here is FINAL, taking precedence over the resolved signing name from both auth scheme resolution and endpoint resolution.

func WithSigV4SigningRegion 

func WithSigV4SigningRegion(region string) func(*Options)

WithSigV4SigningRegion applies an override to the authentication workflow to use the given signing region for SigV4-authenticated operations.

This is an advanced setting. The value here is FINAL, taking precedence over the resolved signing region from both auth scheme resolution and endpoint resolution.

Types

type AuthResolverParameters 

type AuthResolverParameters struct {
	// The name of the operation being invoked.
	Operation string

	// The region in which the operation is being invoked.
	Region string
}

AuthResolverParameters contains the set of inputs necessary for auth scheme resolution.

type AuthSchemeResolver 

type AuthSchemeResolver interface {
	ResolveAuthSchemes(context.Context, *AuthResolverParameters) ([]*smithyauth.Option, error)
}

AuthSchemeResolver returns a set of possible authentication options for an operation.

type Client 

type Client struct {
	// contains filtered or unexported fields
}

Client provides the API client to make operations call for Amazon QLDB Session.

func New 

func New(options Options, optFns ...func(*Options)) *Client

New returns an initialized Client based on the functional options. Provide additional functional options to further configure the behavior of the client, such as changing the client's endpoint or adding custom middleware behavior.

func NewFromConfig 

func NewFromConfig(cfg aws.Config, optFns ...func(*Options)) *Client

NewFromConfig returns a new client from the provided config.

func (*Client) Options 

func (c *Client) Options() Options

Options returns a copy of the client configuration.

Callers SHOULD NOT perform mutations on any inner structures within client config. Config overrides should instead be made on a per-operation basis through functional options.

func (*Client) SendCommand 

func (c *Client) SendCommand(ctx context.Context, params *SendCommandInput, optFns ...func(*Options)) (*SendCommandOutput, error)

Sends a command to an Amazon QLDB ledger.

Instead of interacting directly with this API, we recommend using the QLDB driver or the QLDB shell to execute data transactions on a ledger.

  • If you are working with an AWS SDK, use the QLDB driver. The driver provides a high-level abstraction layer above this QLDB Session data plane and manages SendCommand API calls for you. For information and a list of supported programming languages, see Getting started with the driverin the Amazon QLDB Developer Guide.

  • If you are working with the AWS Command Line Interface (AWS CLI), use the QLDB shell. The shell is a command line interface that uses the QLDB driver to interact with a ledger. For information, see Accessing Amazon QLDB using the QLDB shell.

	// Parameter is
	// required.
	//
	// AWS::Region
	Region *string

	// When true, use the dual-stack endpoint. If the configured endpoint does not
	// support dual-stack, dispatching the request MAY return an error.
	//
	// Defaults to
	// false if no value is provided.
	//
	// AWS::UseDualStack
	UseDualStack *bool

	// When true, send this request to the FIPS-compliant regional endpoint. If the

	// provided.
	//
