oslo.versionedobjects

oslo.versionedobjects library deals with DB schema being at different versions than the code expects, allowing services to be operated safely during upgrades. It enables DB independent schema by providing an abstraction layer, which allows us to support SQL and NoSQL Databases. oslo.versionedobjects is also used in RPC APIs, to ensure upgrades happen without spreading version dependent code across different services and projects.
