Class TransactWriteItemsEnhancedRequest

java.lang.Object

software.amazon.awssdk.enhanced.dynamodb.model.TransactWriteItemsEnhancedRequest

@ThreadSafe
public final class TransactWriteItemsEnhancedRequest
extends Object

Defines parameters used for the transaction operation transactWriteItems() (such as DynamoDbEnhancedClient.transactWriteItems(TransactWriteItemsEnhancedRequest)).

A request contains parameters for the different actions available in the operation:

• Write/Update items through put and update actions
• Delete items
• Use a condition check

It's populated with one or more low-level requests, such as TransactPutItemEnhancedRequest and each low-level action request is associated with the table where the action should be applied. On initialization, these requests are transformed into TransactWriteItem and stored in the request.

Method Details

builder

public static TransactWriteItemsEnhancedRequest.Builder builder()

Creates a newly initialized builder for a request object.

clientRequestToken

public String clientRequestToken()

Providing a ClientRequestToken makes the call to TransactWriteItems idempotent, meaning that multiple identical calls have the same effect as one single call.

A client request token is valid for 10 minutes after the first request that uses it is completed. After 10 minutes, any request with the same client token is treated as a new request. Do not resubmit the same request with the same client token for more than 10 minutes, or the result might not be idempotent.

If you submit a request with the same client token but a change in other parameters within the 10-minute idempotency window, DynamoDB returns an IdempotentParameterMismatch exception.

transactWriteItems

public List<TransactWriteItem> transactWriteItems()

Returns the list of TransactWriteItem that represents all actions in the request.
