Flink CDC 里3台768G内存的机器跑1000个flink job合理吗？

尝试在3台768G内存机器上跑1000个Flink任务，但面临配置问题导致任务无法正常运行。尽管调整了Yarn虚拟内存至超过物理内存，配置JobManager为1024可以运行880个任务，仍然存在内存分配不均和Swap满载的问题。调整单个任务的TaskManager（默认1500）后仍出现内存溢出，有解决办法吗？

Flink CDC里任务失败会自动清除其他机器的checkpoint文件，只保留本机吗？

Flink CDC里任务失败会自动清除其他机器的checkpoint文件，只保留本机的checkpoint么？我这个问题就是 taskmanager1执行任务然后挂掉了，重启，taskmanager2接手这个任务，但是在2这个机器里找不到checkpoint的文件。
