Operator one can pass on event data to operator two, in a pipeline, through GoLang channel, if implemented in GoLang. This helps avoid separation of concerns, amidst runtime failure.

运算符1可以通过GoLang通道(如果在GoLang中实现)在管道中将事件数据传递给运算符2。这有助于避免在运行时失败时分离关注点。

Does flink operator pass on event to another operator through a direct method call or through some Queuing technique?

Flink操作符是通过直接方法调用还是通过某种排队技术将事件传递给另一个操作符？

Does flink operator pass on event to another operator through a direct method call or through some Queuing technique?

That depends. Two or more operators in an operator chain (operators connected only by forward connections) pass events through direct method calls. Otherwise the messages are serialized and sent either via shared memory buffers (if the operators are in the same JVM) or via the network.

那得看情况了。运算符链中的两个或多个运算符(仅通过前向连接连接的运算符)通过直接方法调用传递事件。否则，消息将被序列化并通过共享内存缓冲区(如果运营商位于同一JVM中)或通过网络发送。
