Lifecycle of Notification Download Staging

The download receiver processes NDS records based on their status. The following diagram describes the lifecycle of an XAI type NDS.


The figure illustrates how an NDS record moves from one status to another in its lifecycle.

The following points describe the diagram:

  • Records are created in pending status. A user may transition the record to the canceled state.
  • The MPL processes records in pending and retry status. While the record is being processed, it is changed to in progress.
  • Based on the results of the processing, records could be transitioned to error or complete.
    Note: An NDS is set to error if there is a problem with the NDS or if any of its related XDS records are in error.
  • A user may cancel a record in the error state or change the status to retry to have the MPL try again.
