org.wso2.carbon.mediation.initializer.persistence.MediationPersistenceManager
Manages all persistence activities related to mediation configuration. Takes care of saving configurations to the file system, registry and updating such configurations as and when necessary. All the mediation components (proxy services, sequences etc) should use this implementation to handle their persistence requirements. This class does not immediately carry out persistence requests. Requests are first queued up and then executed as batch jobs. Therefore admin services which initiate persistence requests does not have to 'wait' for disk and network I/O often associated with persistence activities. This improves the UI response times and system usability in a great deal.
