Class ClusterSafeScheduledJobDao

java.lang.Object

com.atlassian.confluence.schedule.persistence.dao.ClusterSafeScheduledJobDao

All Implemented Interfaces:

ScheduledJobDao

@Internal
public class ClusterSafeScheduledJobDao
extends Object
implements ScheduledJobDao

Provides a partial implementation of ScheduledJobDao, and is a stripped-down version of CachedScheduledJobDao. The job configuration functions remain intact (using Bandana), but the job status and history functions have been stubbed out due to their non-performant implementations in CachedScheduledJobDao. The job status and history functions, however, have been stubbed out, as their use required a distributed cache for consistentcy, but the performance was poor. Stubbing those functions out is the safer option, even though it effectively means that those functions are not available in the Scheduler Admin UI.

5.6
