Specifies how to handle detected number columns. DynamoDB returns number values with a total precision of 38.
By default, all numbers will be specified as double. However, depending on your needs, you may wish to handle number columns as either double or decimal. In addition, you can also set the value to string to report all number columns as strings if you are using the CData BizTalk Adapter for Amazon DynamoDB in an environment that cannot handle the maximum precision size of DynamoDB.
