Kafka>=1.1:显式设置max.in.flight.requests.per.connection可以为1<=max.in.flight.requests.per.connection<=5;建议设置为5。 retries 在顺序场景下,建议指定重试参数,retries在不同版本,有不同的默认行为,在Kafka <= 2.0,默认为0;Kafka >= 2.1,默认为Integer.MAX_VALUE,即2147483647;建议顺序场景,显式设置...
因为它只对你的操作系统有要求,比如 Windows 上编译的动态库是 .dll 文件,Linux 上编译的动态库是 .so 文件,只要操作系统一致,那么任何提供了 ctypes 模块的 Python 解释器都可以调用。这种方式的使用场景是 Python 和 C / C++ 不需要做太多的交互,比如嵌入式设备,可能只是简单调用底层驱动提供的某个接口而已。
MSDN中关于rand的描述"The rand function returns a pseudorandom integer in the range 0 to RAND_MAX (32767). Use the srand function to seed the pseudorandom-number generator before calling rand."rand()产生的伪随机数的范围是0到32767，一般想要产生比如[5,125]的随机数，可以这么写：int...

The strtof and wcstof functions failed to set errno to ERANGE when the value wasn't representable as a float. This error was specific to these two functions; the strtod, wcstod, strtold, and wcstold functions were unaffected. This issue has been fixed, and is a runtime breaking change. ...
