The DynamoDBMapper has an API for retrieving multiple items from multiple tables based on the primary key, which is documented here.

The method you're looking for is

public java.util.Map<java.lang.String,java.util.List<java.lang.Object>> 
         batchLoad(java.util.Map<java.lang.Class<?>,java.util.List<KeyPair>> itemsToGet)

Where the KeyPair will be used to list your Hash/Range keys
