Playing with java code generator (cglib) to write testable M1 data loader. This is a PoC that shows that it's easy to produce efficient code that loads quickly at runtime while accessing selected fields from the business objects inside M1 databases. Additionally, annotations make it possible to specify which data relationships and attributes clients are interested in from the data model. This project is not intended to be used as is. It introduces M1 users with a flexible design that can be loaded/unloaded at runtime in a selectively manner, without any service disruption.
