Examples with TransactPutItemEnhancedRequest software.amazon.awssdk.enhanced.dynamodb.model.TransactPutItemEnhancedRequest used on opensource projects

Example 1 with TransactPutItemEnhancedRequest

use of software.amazon.awssdk.enhanced.dynamodb.model.TransactPutItemEnhancedRequest in project aws-sdk-java-v2 by aws.

the class PutItemOperation method generateRequest.

@Override

    if (!TableMetadata.primaryIndexName().equals(operationContext.indexName())) {
        throw new IllegalArgumentException("PutItem cannot be executed against a secondary index.");
    }
    TableMetadata tableMetadata = tableSchema.tableMetadata();
    // Fail fast if required primary partition key does not exist and avoid the call to DynamoDb
    tableMetadata.primaryPartitionKey();
    boolean alwaysIgnoreNulls = true;
    T item = request.map(PutItemEnhancedRequest::item, TransactPutItemEnhancedRequest::item);
    Map<String, AttributeValue> itemMap = tableSchema.itemToMap(item, alwaysIgnoreNulls);
    WriteModification transformation = extension != null ? extension.beforeWrite(DefaultDynamoDbExtensionContext.builder().items(itemMap).operationContext(operationContext).tableMetadata(tableMetadata).tableSchema(tableSchema).operationName(operationName()).build()) : null;
