Add Transaction for DynamoDB using Document Interfaces or Object Persistence Interface

[hanslai]

#25 has been 6 years.
There are really little document on .net or .net core.
And seems impossible to do it in Document Interfaces or Object Persistence Interface.

Thanks for voicing your interest. I'm going to close this out as a duplicate of #1453. If you have any more comments to add about your use case or how you would prefer the implementation to look like, please comment there.

How hard can this possibly be? Transaction support is already in the low level library, I would assume the high level libraries are just handling type serialization and such... so how hard is it to add the transactional version of the batching methods?

For anyone looking for a workaround, you can combine the low-level api with high-level api serialization by doing something like:

    var dynamoDbClient = new AmazonDynamoDBClient();
    var dynamoDbContext = new DynamoDBContext(dynamoDbClient);
    var item1 = new MySampleItem();
    var item2 = new MySampleItem();
    await dynamoDbClient.TransactWriteItemsAsync(new TransactWriteItemsRequest()
    {
      TransactItems = new List<TransactWriteItem>
      {
        new TransactWriteItem()
        {
          Put = new Put()
          {
            Item = dynamoDbContext.ToDocument(item1).ToAttributeMap(),
            TableName = dynamoDbContext.GetTargetTable<MySampleItem>().TableName
          },
        },
        new TransactWriteItem()
        {
          Put = new Put()
          {
            Item = dynamoDbContext.ToDocument(item2).ToAttributeMap(),
            TableName = dynamoDbContext.GetTargetTable<MySampleItem>().TableName
          }
        },
      }
    });
