我这边有一个作业，每小时大概有84W的数据量进来，然后业务延时特别高，想请教一下Flink中jm、tm和并行度怎么分配资源合适？作业参考：https://vvp.console.aliyun.com/web/d37a7343e1354f/zh/#/workspaces/d37a7343e1354f/...

Flink我创建了一个cdc任务，并且使用的是简单模式，在增量阶段增大并行度，会不会造成浪费资源？

Flink我创建了一个cdc任务，并且使用的是简单模式，在增量阶段增大并行度，会不会造成浪费资源，他后续算子会进行数据均衡吗？当我所有的算子都chain在一起的时候，会浪费资源吗？还是说他只能使用一个并行度的资源？

Flink CDC里做了服务器迁移，资源大小都是一样，为什么做ck的时长比原先慢了很多？

Flink CDC里做了服务器迁移，资源大小都是一样，为什么做ck的时长比原先慢了很多，有些慢了50%，使用的mysqlcdc2.2.1+flink1.13.6+doris，有没有大佬能指导下？
