    Description

      If the blocking plan used by the CachedPlanStage fails during execution and falling back to the backup plan is required, the following should be written to QLOG:

      • A message indicating that the backup plan is being switched to.
      • The current execution stats for the blocking plan.
      • The error message corresponding to the failure of the blocking plan, if an error message is available.

      Currently, the CachedPlanStage does no logging when switching to the backup plan.
