            Summary
            
              - Introducing timestamp is mandatory to achieve the C* full migration
- Auto IDs could be corrupted in recovery & replication cases
- Timestamp are more reliable to synchronize asynchronously two databases
- Timestamp provide millisecond precision instead of minutes for REF_TIMES_ID
- SQL queries using REF_TIMES_ID are really painful to read & write
