public class RemovePeopleDirectoryDuplicatesUpgradeTask
extends AbstractDeferredRunUpgradeTask
implements DatabaseUpgradeTask

The index flushing strategy is (intentionally) inaccurate and relies on an in-memory 'flushed entries' cache to prevent the same object being flushed twice. This risks duplicate entries being created in the index immediately after the application is restarted if the most recently queued index task entries prior to the restart are AddDocumentIndexTasks. See CONF-29072 for additional details. Therefore, this upgrade task changes any recent 'ADD' index task entries in the database to 'UPDATE' tasks instead, and from this point forward we no longer create 'ADD' entries in isolation. This upgrade task also re-indexes existing PersonalInformation objects to remove any duplicate entries in the people directory.

Method Detail


public boolean runOnSpaceImport()
Description copied from interface: BackupSupport
Returns true if an older Space can't be imported in a new instance without running this task. For example:

Note that tasks don't run on space import yet, so we just reject the import in this case.

Specified by:
runOnSpaceImport in interface BackupSupport


public boolean breaksBackwardCompatibility()
Description copied from interface: BackupSupport
Returns true if a new export can't be imported in an older instance. Breaking compatibility means a snapshot of the new version will not work at all with the previous version. For example: The best way to test is whether a newer export can be imported (with fully working features) in an older instance.

Specified by:
breaksBackwardCompatibility in interface BackupSupport


public void doDeferredUpgrade()
                       throws Exception
Description copied from interface: DeferredUpgradeTask
Run the upgrade that was deferred by an earlier call to doUpgrade.

Specified by:
doDeferredUpgrade in interface DeferredUpgradeTask


public String getBuildNumber()
Specified by:
getBuildNumber in interface UpgradeTaskInfo
getBuildNumber in class AbstractUpgradeTask
The build number that this upgrade is applicable to
