异步调用，分布式事务不存在，数据库回滚

## Ask your question here
异步调用Dubbo服务，调用方执行完成，分布式事务已经commit。但是Dubbo服务提供方耗时原因，还在执行中，导致出现错误Transaction doesn't exist，服务提供方数据回滚，从而出错。现在的问题就是：都使用了异步调用，为什么还会存在事务在服务提供方，当我使用异步调用的时候，如何才能阻止事务的传递？

Start by reviewing Dubbo's asynchronous invocation and distributed transaction propagation behavior, using the reported provider delay and “Transaction doesn't exist” error as the reproduction scenario. Confirm whether the provider transaction is expected to remain active and document the configuration or behavior that prevents unintended propagation; no source files or tests are identified in the issue.
