Doing a conditional update in dynamodb with the data model

Question

Is it possible to do a conditional update of an item in dynamodb using the data model as you can with the document model? If there isn't a way to do a conditional update does the .Net SDK have a method to convert an object into an UpdateItemRequest object?

Answer 1

Take a look at the UpdateExistingAttributeConditionally method for an example of how to perform a conditional update on an item in DynamoDB using the .NET SDK data model. You can also set a ConditionExpression using the document model when using the midlevel sdk for .NET.
