   Hi, Since this thread is a little long, I do not track them all, but I'd like to give some inputs.
   
   ```sql
   set autocommit = 0;
   xa begin ...
   xa commit ...
   ```
   Actually, `set autocommit = 0` hints an implicit `COMMIT`, so you will see these coding here,
   ```java
   if (((SetAutoCommitStatement) tclStatement).isAutoCommit()) { 
            return backendConnection.getTransactionStatus().isInTransaction() 
                    ? new TransactionBackendHandler(tclStatement, TransactionOperationType.COMMIT, backendConnection) : new SkipBackendHandler(tclStatement); 
        } 
   ```
