kafka有同步(sync)、异步(async)以及oneway这三种发送方式,某些概念上区分也可以分为同步和异步两种,同步和异步的发送方式通过“producer.type”参数指定,而oneway由“request.require.acks”参数指定。 1. sync vs async 在官方文档Producer Configs中有如下: 翻译过来就是: producer.type的默认值是sync,即同步的方式。

术语“ sync”和“ async”指的是编写使用并发的应用程序的两种方式。所谓的“sync”服务器使用线程和进程的底层操作系统支持来实现这种并发。以下是同步部署的效果图: 在这种情况下,我们有五个客户端,所有客户端都向应用程序发送请求。这个应用程序的公共访问点是一个 web 服务器,它充当一个负载均衡器,将请求分发...
II - Sync V.S. Async On windows platform, Async I/O is also called Overlapped I/O. In Winsock 2, you create an overlapped socket using WSASocket() with the WSA_FLAG_OVERLAPPED flag, or simply using the socket() API. You can use the Win32 file I/O APIs or Winsock 2 WSASend(...
阻塞(Blocking),非阻塞(Non-Blocking),同步(Sync),异步(Async),重叠(Overlapped)。 首先要明确的是,只有那些会导致发生“数据传输”的函数(accept,connect,send,recv等)才存在这些概念;像bind、listen这些不会引发“数据传输”的函数,是不存在“阻塞非阻塞”或“同步异步”这样的问题的。
I'm curious about using synchronous vs. asynchronous calls. In this reddit thread: https://www.reddit.com/r/cpp/comments/5s8s2f/is_there_efficient_alternative_to_asio/ you indicated sync. is more performant than async. I believe I've read this elsewhere but it seems to contradict everythin...

There’s an option you can use to turn off both safety nets: HttpContext.AllowAsyncDuringSyncStages (it can also be set in web.config). A few pages on the Internet suggest setting this whenever you see these exceptions. I can’t disagree more vehemently. Seriously, I...
