用户态的执行主要是ASYNC_start_job,另一个asyn job(async job func)的执行线是async_start_func。 通过async_fibre_makecontext完成在用户态和async job的来回切换。 三、应用场景:SSL硬件加速卡QAT 当硬件加速卡操作执行的时候,通过async_fibre_makecontext进行用户切换到用户态操作,而后用户态需要主动poll,判断asyn...

Starts all child jobs asynchronously. When all child jobs are started, StartJobCompleted event is raised.
If you start the ASYNC jobs and the ASYNC subsystem is not running, the status of the CNTL_ASYNC job will be *JOBQ. The status will change to *ACTIVE as soon as the ASYNC subsystem is up.Scheduling when the Async Jobs Start: You can create a schedule for a periodic process that ...

如果你希望并行执行两个或更多的任务,你必须像在parallel中一样使用await Promise.all([job1(), job2()])。 async/await和Promise#then对比以及错误处理 大多数async函数也可以使用Promises编写。但是,在错误处理方面,async函数更容易捕获异常错误 上面例子中的concurrentStart函数和concurrentPromise函数在功能上都是等效...
The method that start async job can not be transactional. You can change the spring transaction config ,for example ,remove the annotation@transactionalfrom the method. But starting processes and completing tasks are almost transactional, for rollback while failed. ...
可选的,async 可以通过将 start 参数设置为 CoroutineStart.LAZY 而变为惰性的。 在这个模式下,只有结果通过 await 获取的时候协程才会启动,或者在 Job 的 start函数调用的时候。运行下面的示例: valtime = measureTimeMillis {valone = async(start = CoroutineStart.LAZY) { doSomethingUsefulOne() }valtwo =...
