Force delete on table that uses optimistic locking with version number

Question

I have a Dynamo table that uses optimistic locking via the DynamoDBVersionAttribute to ensure that only one worker at a time has a document reserved. However, when I want to clean up a document, the delete throws a ConditionalCheckFailedException when I don't set the version in the DynamoDBMapper.

At that point, I don't care what version the document is, and I want to delete it no matter what version it is. Is there a way to force the delete without worrying about the version? I want to overcome the exception without having to query Dynamo for the document.

Answer 1

You can delete the item by specifying the SaveBehaviour as CLOBBER without worrying about the version.

DynamoDBMapper mapper;
mapper.delete(object, new DynamoDBMapperConfig(DynamoDBMapperConfig.SaveBehavior.CLOBBER)
