aiomultiprocess github.com/omnilib/aiom 结合asyncio与multiprocessing。核心在于实现了异步版本的多进程multiprocessing,可以发挥异步和多进程并发的双重优势。编码难度较大,需要同时管理异步任务和进程间协调。它提供了异步友好的进程池,可以通过async/await的方式发起多进程运行异步任务,并使用异步方式获取结果 vs multiproce...

协程async、await关键字yieldfromyield关键字yield是控制流程工具,yieldfrom(3.3引入的关键字)就是打开了一个双向通道,把外层调用方和最内层的子生成器连接起来 asyncio是python3.4引入的库async、await关键字是python3.5引入的关键字,也是现在最推荐的实现协程对象的方法。因为之前yield、yieldfrom容易和生成器混淆,不能一...
需要强调的是:此操作并不会在所有池工作进程中并执行func函数。如果要通过不同参数并发地执行func函数,必须从不同线程调用p.apply()函数或者使用p.apply_async() 2 p.apply_async(func [, args [, kwargs]]):在一个池工作进程中执行func(*args,**kwargs),然后返回结果。此方法的结果是AsyncResult类的实例,...

all tasks need to voluntarily suspend and return control to the loop in a timely manner. To benefit from the async style, an application needs to have tasks that are often blocked by I/O and don't have too much CPU work. Web applications are normally a very good fit, in particular if...
