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

我用的Flink1.7,CDC版本2.3的，有没有的类似代码给一个，看看是不是哪里配置少了？

我用的Flink1.7,CDC版本2.3的，这种initial模式理论上是第一次同步全量数据，后面如果再启动，只要flink保存了checkpoint，里面应该有程序停止前的scn位置吧，下次启动不会再全量读了，从上次的scn开始读，有没有的类似代码给一个，看看是不是哪里配置少了？
