   Well, there is a long disscusion with this issue and two related PR #13187 and #13362 . I'd like to say
   
   - It is a lack of documents to understand the sharding sphere transaction desgin, does anybody point out if I miss it ?
   - There is a confusion between ```TransactionType.XA``` and using XA scenario with ```sharding-proxy```.
   - It seem that we change the semantics of some transaction statments, such as ```set autoCommit```.
   
   And  I think it is very important of the transactional functions of sharding sphere especially in production system which is concerned about the data consistency.
   
   It should have a good chance to talk about this issue in the meetup but unfortunately we missed it due to COVID-19. Anyway, I think it could be helpful to have this disscusion face to face and it might be much clearer understand. Although this issue could be a very hard and tough, I believe that we can resolve it finally because **WE ARE GREAT TEAM**.
   
   Feel free to schedul a online meeting for disscussion if you think this is necessary. @roodkcab @RaigorJiang @TeslaCN @tristaZero @jingshanglu
