Interface QldbSessionClient

All Superinterfaces:

AutoCloseable, SdkAutoCloseable, SdkClient

@Generated(value="software.amazon.awssdk:codegen")
public interface QldbSessionClient
extends SdkClient

Service client for accessing QLDB Session. This can be created using the static builder() method.

The transactional data APIs for Amazon QLDB

Instead of interacting directly with this API, we recommend that you use the Amazon 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 qldbsession data plane and manages SendCommand API calls for you. For information and a list of supported programming languages, see Getting started with the driver in 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.

Parameters:

sendCommandRequest -

Returns:

Result of the SendCommand operation returned by the service.

Throws:

BadRequestException - Returned if the request is malformed or contains an error such as an invalid parameter value or a missing required parameter.

InvalidSessionException - Returned if the session doesn't exist anymore because it timed out or expired.

OccConflictException - Returned when a transaction cannot be written to the journal due to a failure in the verification phase of optimistic concurrency control (OCC).

RateExceededException - Returned when the rate of requests exceeds the allowed throughput.

LimitExceededException - Returned if a resource limit such as number of active sessions is exceeded.

SdkException - Base class for all exceptions that can be thrown by the SDK (both service and client). Can be used for catch all scenarios.

SdkClientException - If any client side error occurs such as an IO related failure, failure to get credentials, etc.

QldbSessionException - Base class for all service exceptions. Unknown exceptions will be thrown as an instance of this type.

This is a convenience which creates an instance of the SendCommandRequest.Builder avoiding the need to create one manually via SendCommandRequest.builder()

Parameters:

sendCommandRequest - A Consumer that will call methods on SendCommandRequest.Builder to create a request.

Returns:

Result of the SendCommand operation returned by the service.

Throws:

BadRequestException - Returned if the request is malformed or contains an error such as an invalid parameter value or a missing required parameter.

InvalidSessionException - Returned if the session doesn't exist anymore because it timed out or expired.

OccConflictException - Returned when a transaction cannot be written to the journal due to a failure in the verification phase of optimistic concurrency control (OCC).

RateExceededException - Returned when the rate of requests exceeds the allowed throughput.
