The transaction coordination diagram is used to show the constituents of a defined transaction, the order of processing (sequential vs. parallel), and nested transactions.
允许嵌套会导致内部事务成功，但父事务仍旧可以失败的情况——那么您如何回滚先前提交了的子事务呢？
Permitting nesting leads to situations where the internal transactions succeed, but the parent can still fail — so how do you roll back previously committed children?
