I am deleting a non-existing record from the dynamodb table using dynamoDbMapper.delete(object) which uses default DynamoDBDeleteExpression
I was expecting some sort of exception to arise since the record is absent from the DB but it does nothing. It does not even have a return type which could tell if the delete was successful or failure. Is there a way to add a delete expression or something which will make my delete throw an exception if the item is absent from the db?
It is by design:
Unless you specify conditions, the DeleteItem is an idempotent operation; running it multiple times on the same item or attribute does not result in an error response.
