Override aws-request-id in java sdk

Hey thanks for your reply, I'm trying this but not working for me

 AwsRequestOverrideConfiguration awsRequestOverrideConfiguration = AwsRequestOverrideConfiguration.builder()
                .putHeader("aws-request-id", "123345")
                .build();
        PutItemRequest putItemRequest = PutItemRequest.builder()
                .item(stringAttributeValueMap)
                .tableName(getTableName())
                .overrideConfiguration(awsRequestOverrideConfiguration)
                //.overrideConfiguration(s -> s.putHeader("x-amz-request-id", awsRequestId))
                .returnValuesOnConditionCheckFailure(ReturnValuesOnConditionCheckFailure.ALL_OLD)
                .conditionExpression(expression.expression())
                .build();

 try {
dbclient.putItem(putItemRequest);
        } catch (ConditionalCheckFailedException exception) {
               exception.requestId() // not what i've sent
            throw new RecordAlreadyExists("value %s for field %s already exists ".formatted("uniqueKeyAttributeName", "uniqueKeyAttributeName"),
                    exception);
        }

Yes, it is possible to pass a custom AWS request ID when using the DynamoDB Java SDK (v2.29.17). You can achieve this by using the request override configuration feature provided by the SDK.

To set a custom AWS request ID, you can use the AwsRequestOverrideConfiguration class. This class allows you to add custom headers to your request, including the 'aws-request-id' header.

Here's how you can do it:

1. Create an AwsRequestOverrideConfiguration object with your custom request ID.
2. Add this configuration to your DynamoDB request using the overrideConfiguration() method.

For example, if you're using the ExecuteStatementRequest.Builder, you can do something like this:

String customRequestId = "your-custom-request-id";

AwsRequestOverrideConfiguration overrideConfig = AwsRequestOverrideConfiguration.builder()
    .putHeader("aws-request-id", customRequestId)
    .build();

ExecuteStatementRequest request = ExecuteStatementRequest.builder()
    .statement("Your PartiQL statement")
    .overrideConfiguration(overrideConfig)
    .build();

This approach allows you to set a custom AWS request ID for your DynamoDB operations. However, it's important to note that while you can set this custom ID, the service may still generate its own request ID for internal tracking purposes.

Remember that each request includes a request ID by default, which can be useful for diagnosing issues with AWS Support. If you're overriding this ID, make sure to keep track of both your custom ID and the one returned by AWS for comprehensive request tracking.
