> DynamoDBIO uses the old style API ScanRequestAPI, translating into the
> ScanSpec
> API can bring us improvements because we can eventually align Scans and
> Querys
> in the DynamoDBIO API. Also this is needed for migration to AWS SDK for Java
> 2.x.
> We should use for this the new ScanSpec API.
