Flink CDC我配置mysql CDC，但任务重启（重新执行）后，它总是全量同步数据，要怎么做？

Flink CDC里我配置mysql CDC，但是任务重启（重新执行）后，它总是全量同步数据，具体有什么参数可以配置使用增量同步啊？

Flink CDC你们cdc配置db.*,如果库里频繁加表，你们是咋操作的，一加表就重启任务？

Flink CDC你们cdc配置db.*,如果库里频繁加表，你们是咋操作的，一加表就重启任务？不生效啊，任务一直运行着，库里新建一个表，如果不重启任务，增量数据都进不去,只能savepoint，然后savepoint恢复任务,不及时恢复任务，那么后面这个表的历史数据会丢失,除非在任务初始化的时候指定表名，全量启动，后面新建的表，再加到配置里，然后恢复启动不会有问题

Flink CDC作业连接配置没问题，总报不能初始化，一直重启？

Flink CDC按你上午的那种配置写法，我把整个flink环境重启了他才生效的。但又没完全起作用？

Flink CDC按你上午的那种配置写法，我把整个flink环境重启了他才生效的。但又没完全起作用，我配了3个，刚开始他突破到了4个，后来又失败稳定在3个了。如果flink之前已经按默认20个提交过任务，即使把所有的任务都退出，重新提交新的任务都设置的3也是不起作用的，我依然提交了9个任务。重启之后所有任务都设置3，后面的任务运行就总是失败了？
