推荐答案

LocalExecutionEnvironment启动了Flink MiniCluster，该MiniCluster在单个JVM中运行整个Flink系统(JobManager，TaskManager).因此，您仅限于一台计算机上可用的CPU内核和内存.您也没有多个JobManager的HA.我没有看过MiniCluster环境的其他限制，但是我敢肯定还有更多限制.

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.
