在对应系统的JVMInit的方法中, 会调用java.c中的ContinueInNewThread方法,并在方法ContinueInNewThread中调用不同操作系统的ContinueInNewThread0方法,如下图所示: 这样我们就来到了第一天,用Clion调试JDK源码时的JavaMain方法 JavaMain 方法 这里还是以打印版本号为例,可以看到在444行,有如下代码: 代码语言:javascript...
图片来源:https://ci.apache.org/projects/flink/flink-docs-master/docs/concepts/flink-architecture/ 图中两个TaskManager节点共有6个slot,5个SubTask,其中sink的并行度为1,另外两个SubTask的并行度为2。此时由于Subtask少于Slot个数,所以每个Subtask独占一个Slot,没有SlotSharing。下面我们把把并行度改为6: 图...
