请问flink cdc 使用CDAS语法实时同步整库的时候，如果库里面新加一张表，是怎么处理的？

问题1：请问flink cdc 使用CDAS语法实时同步整库的时候，如果库里面新加一张表，是怎么处理的，又全量同步一遍？后加表，从savepoint 恢复是不行的，不会同步数据，还会在日志中保错schema不对，工单提了让我全量同步，或者新开一个任务。问题2：我发现并没有这样，我任务同步开启了，但是库里面新加了一张表，FLink 这边只同步了表结构，没有同步数据。源表数据没自动增加到目标表，只是....

在flink，cdas语法如何整库同步从mysql到paimon能，有文档介绍吗？

在flink，cdas语法如何整库同步从mysql到paimon能，有文档介绍吗？参考hologres的不成功前台调试不成功，但是我直接上线了作业运行成功，可能是开发界面的sql校验还没集成，上线部署后也是有问题，会报错大量空指针问题，看来需要一个文档参考下，可能有地方是不对的
