As long as distributed systems are involved, distributed transactions will be encountered no matter what. Of course, you can split the system reasonably and plan the structure of tables and libraries, but this only reduces the number of distributed transactions. For example, your original system There will be distributed transactions in 5 places. Now after optimization, there may only be 3 places, but if you don't have any, I personally think it is not feasible.
