flink cdc 读取MySQL数据，这种一般手动指定是u不是会规避这种情况？

在使用Flink CDC读取MySQL数据时，如果没有手动指定server-id，会报告有相同的server-id错误。一般来说，手动指定server-id可以规避这种情况。但是，手动指定server-id时如何确保与MySQL主从同步使用的不重复？又如何知道哪些server-id尚未使用？另外，为什么Flink CDC默认分配的server-id会重复？

Flink CDC会出现分配和之前任务相同的是吗？

Flink CDC任务指定了server-id后面在启动别的cdc任务但是没有指定server-id可能会导致新的任务去随机分配server-id的时候，会出现分配和之前任务相同的是吗？

Flink CDC中为什么只使用一个插槽，明明给他分配了八个？我设置了八个，但是任务只在一个上面跑，

Flink CDC中为什么只使用一个插槽，明明给他分配了八个？我设置了八个，但是任务只在一个上面跑，按道理这八个，都应该有数据流转啊，就是普通的MySQL到MySQL
