Derived data generation and storage

Abstract:

A data storage service obtains derivation code and data. The derivation code is executable to generate derived data from the data. The data storage service stores the derivation code and the data in a logical data container. In response to receiving a request to obtain the derived data, the data storage service uses the derivation code to regenerate the derived data from the data and transmits the derived data to fulfill the request.
