This pool is also destroyed when all the actuators in the worker pool are closed. When an actuator is created in the Verticle, Vert.x will automatically destroy the period when the verticle is loaded. The work executor can be configured at the time of creation. int poolsize = 10; 2 minutes Long maxexecutetime = 120000; Workerexecutor executor =vertx.cre

asynchronous operations when we need them, and secondly it provides thread creation strategies (such as the ability to create threads by delaying loading). Makes it possible to create threads in a variety of ways. Before describing the specific use of async and why you should use Std::async instead of creating threads, I would like to first say Std::future, std::p romise and std::p ackaged_task.Std::futureStd::future is a very useful and interesting thing, simply said Std::future provides a mec

Also, this should be a part of the test system: block illegal data. In fact, the foreground progra

-thread communication can avoid overhead on the use of mutex locks. This can be achieved by accessing the memory through atomic operations. For different situations, we can change the visibility of the Access Memory action through the explicit memory barrier. For asynchronous transmission between threads, the C ++ 11 standard library is added andstd::packaged_taskIt is used to encapsulate a function call that will return asynchronous results.
