The unification of single-threaded and multi-threaded and asynchronous and distributed
“Fire-and-Forget” is a guidance bullet with independent guidance capability. It does not need external support, it will automatically track and strike the target, and do not need to control after launching. The utility model has the advantages of improving the use efficiency between the missile and the launcher, and reducing the missile’s dependence on other systems to provide its own updated information, so that the launcher can attack the largest number of targets in the shortest time and improve the survival of the launcher. The development direction of guidance technology in the future is precisely the “Fire-and-Forget” precision guidance technology.
For the same reason, I think the development direction of concurrent and parallel programming technology is also “Fire-and-Forget”, so asynchronous is unnecessary, async / await is a backward and inevitably eliminated model. Change from focusing on “code and function development” to “data control, data flow management, data lifecycle management, data standardization system, process improvement (process reengineering), thread collaborative optimization, etc.”
From the perspective of Operations Research, async/await should be abolished. When waiting, this thread should be over. For example, in a factory, it will not happen that one workshop stops in the middle of the production process and waits for its products at the door of another workshop to continue the production process. Each workshop only interacts with the warehouse. After the main thread (also the workshop) sends out order data, The production plan is generated by the warehouse, and data (messages) are sent to the relevant workshops for production until the task is completed. There is no waiting in the entire process, but the production plan is generated according to the order, with the warehouse as the center, and each workshop independently produces in parallel.
Therefore, asynchronous technology from the perspective of management, people who understand the situation know that they are waiting for raw materials; people who do not understand the situation may mistakenly think that they are on strike. But in any case, it wastes resources greatly.
Existing pragmatic “Fire-and-Forget” concurrency and parallel technology: software transactional memory (STM), multi-versioned concurrency control (MVCC), git.
