Use oslo-versioned-objects to help with dealing with upgrades
The goal of this blueprint is to introduce versioned objects into Trove.
An object is used to bundle data with methods that can operate on them. The plan is to represent the following concepts as objects: .
By using objects, the code will be insulated from the actual database schema, making it easier rolling upgrades. Objects can be used to pass data over RPC and allow lazy-loading of data directly from the database or over RPC.
