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.
