    • currentSynchronyDatasetSize

      public SynchronyRowsCount currentSynchronyDatasetSize(Long contentId)
      Description copied from interface: SynchronyDataService
      If the parameter is not null, returns size of Synchrony history for that entity. If the parameter is null, returns overall Synchrony rows count for the whole instance.
      Specified by:
      currentSynchronyDatasetSize in interface SynchronyDataService

    • softRemoveHistoryOlderThan

      public void softRemoveHistoryOlderThan(int thresholdHours, int contentCount)
      Description copied from interface: SynchronyDataService
      Remove approximately content records from Synchrony history, which are older than and are safe for removal. Execution of this method should avoid any bad effect on users experience because we touch here only content which haven't been updated for hours. This method provides only 'best effort' guarantee for data removal. Deletion strategy depends on the implementation details of how exactly do we determine that content hasn't been touched in and might change. In some edge cases the method will not remove any data. If you're looking for a guaranteed way to clean synchrony history, please look at SynchronyDataService.hardRemoveHistoryOlderThan(int).

      The main purpose of this method is disk space cleanup in collab editing tables. Parameter allows to shift trade-off between removal efficiency (disk reclaiming) and the degree of intrusiveness.

      The method is executed synchronously in the same thread. If exception is thrown somewhere in the middle, it is possible to have only a part of data removed, because the removal might happen in several transactions, but remaining data will always stay consistent (e.g. synchrony data consistent with content properties).

    • hardRemoveHistoryOlderThan

      public void hardRemoveHistoryOlderThan(int thresholdHours)
      Description copied from interface: SynchronyDataService
      Remove all events from content entities, which have any data older than . Theoretically this might cause last 30 seconds of history disappear. This method is designed to be called rarely and be the last resort for GDPR compliance.

      The method guarantees to remove old personal data in order to be compliant with regulations. If the customer doesn't care about any regulations, it shouldn't generally call the method, instead less intrusive SynchronyDataService.softRemoveHistoryOlderThan(int, int) should be used.

      The method is executed synchronously in the same thread. If exception is thrown somewhere in the middle, it is possible to have only a part of data removed, because the removal might happen in several transactions, but remaining data will always stay consistent (e.g. synchrony data consistent with content properties).

    • removeHistoryFor

      public void removeHistoryFor(ContentId contentId)
      Description copied from interface: SynchronyDataService
      This method removes Synchrony history for given content. It can be used to completely remove Synchrony history and reset sync rev properties for given content. If content is not of a type of Page or BlogPost, IllegalArgumentException is thrown. IMPORTANT: please keep in mind, that this method deletes Synchrony history for provided page or blog. If Synchrony history is needed f.e. to conduct analysis of the problem, caller should fetch and save it BEFORE invocation of this method.
      Specified by:
      removeHistoryFor in interface SynchronyDataService
      Parameters:
      contentId - id of the content, which history has to be cleaned up. Should not be null.

    • removeApplicationCredentials

      public void removeApplicationCredentials(String applicationId)
      Description copied from interface: SynchronyDataService
      Remove application credentials from Synchrony tables
      Specified by:
      removeApplicationCredentials in interface SynchronyDataService
      Parameters:
      applicationId - id of application to remove

    • dataCleanUpAfterTurningOffCollabEditing

      public void dataCleanUpAfterTurningOffCollabEditing(String appId)
      Description copied from interface: SynchronyDataService
      This method cleans up Synchrony data after turning Collaboration Editing off.
      Specified by:
      dataCleanUpAfterTurningOffCollabEditing in interface SynchronyDataService
      Parameters:
      appId - id of application to remove
