Flink作业性能

您可以查看运行中作业的性能，包括Job Manager与运行Task Managers的CPU、内存和线程的使用情况，这可以协助您定位代码问题，例如作业代码是否存在问题、个别类是否初始化比较慢、个别类是否占用资源比较多等问题。本文为您介绍如何查看作业Job Manager和运行Task Managers的性能。

flink1.17.1 + cdc 2.2.1 启动job，做增量同步的功能吗？

使用flink1.17.1 + cdc2.2.1启动的job没有问题，可以连续启动三四个。但是当升级到flink1.17.1 + cdc2.3或更高版本（比如2.4、2.4.2、3.0）时，经常出现无法连接数据库的问题，而且每次提交到第二个或第三个job基本上就一定会出现复制错误。另外我是使用pyflink +flinksql的方式，帮忙看下是怎么回事呢？

想问下Flink CDC job 报错、重试失败退出之后重新拉起作业之后怎么回到之前的增量同步点？

想问下Flink CDC job 报错、重试失败退出之后重新拉起作业之后有办法回到之前的增量同步点继续同步吗？
