在生产者和消费者之间,Python虚拟机是通过Py_buffer传递的。它的结构如下—— typedefstruct{void*buf;PyObject*obj;Py_ssize_tlen;Py_ssize_titemsize;intreadonly;intndim;...}Py_buffer; 来自CPython 3.9 buf指针指向原生的buffer对象,是我们需要直接使用的对象。 obj指向当前Py_buffer的拥有者(有点像rust的...

1、使用 Python 的 pickling库进行序列化和反序列化。这是默认方法,因为pickling库是内置于Python的,但它不能很好地处理schema evolution。而且如果您需要与用 C++ 或 Java 编写的应用程序进行数据通信,也不能很好地工作,毕竟C++和Java可没有pickling库,python用pickling库序列化的数据,C++和Java无法按相同的方式反序...
