Google App Engine - 任务队列名称和事务
In the Google App Engine documentation it says below (see here).
Transactional tasks must not have
user-specified names.
Are tasks within transactions automatically assigned names or is there some other reason for this?

原因是任务名称本身是事务性的，并且不可能将两个原子操作（数据存储事务和获取任务名称）组合成单个原子事务。
The reason for this is that task names are themselves transactional, and it's not possible to combine the two atomic operations (the datastore transaction and obtaining the task name) into a single atomic transaction.
