> It is very appropriate when MultiTableDeltaStreamer completes the business of updating table a' by table a and updating table b' by table b. Because MultiTableDeltaStreamer will start two threads, one to update table a', and the other to update table b'. If the current service scenario is that table a and table b update table c at the same time, MultiTableDeltaStreamer may encounter write conflict and cannot complete the service.
