Class DatabaseClusterLockService

java.lang.Object

com.atlassian.beehive.db.DatabaseClusterLockService

All Implemented Interfaces:

ClusterLockService, ManagedClusterLockService

public class DatabaseClusterLockService
extends Object
implements ManagedClusterLockService

This is the database backed implementation of ClusterLockService that can be used by clustered applications.

This implementation relies on the host application providing SPI implementations for Data Access objects.

Applications whose dependency injection container does not support the JSR-250 PostConstruct annotation will need to explicitly invoke the cleanUpOrphanLocks() method upon startup or the first lock attempt.
