IVI Persistence Manager
Submitted by Bert Michaud, updated on 29 Oct 2009
The Persistence Management component is an abstraction layer between applications and the storage of their configuration data. There are two elements to these components: a storage library and a filesystem-based component.
The Persistence Manager library presents an application framework for the persistent storage of configuration and state data in a configurable backend. This component is very lightweight and easy to embed in a given infotainment application. The GENIVI Platform specifies the persistence manager library and interfaces. The library allows for quick key/value storage and retrieval. It also enables simple transactional changes of configuration and state data to facilitate recovery in an unexpected power down situation.
The filesystem-based approach uses the traditional Linux application state storage mechanism to store data. This mechanism uses the directory /var/lib/ in order to store configuration and state information.
