感谢任何帮助/见解.谢谢

Appreciate any help/insight. Thanks

推荐答案

LocalExecutionEnvironment 启动了一个 Flink MiniCluster，它在单个 JVM 中运行整个 Flink 系统(JobManager、TaskManager).因此，您仅限于该一台机器上可用的 CPU 内核和内存.您也没有来自多个 JobManager 的 HA.我还没有研究 MiniCluster 环境的其他限制，但我确信存在更多限制.

LocalExecutionEnvironment spins up a Flink MiniCluster, which runs the entire Flink system (JobManager, TaskManager) in a single JVM. So you're limited to CPU cores and memory available on that one machine. You also don't have HA from multiple JobManagers. I haven't looked at other limitations of the MiniCluster environment, but I'm sure more exist.
