因为Flink CDC源表不是不能定义watermark嘛，那我可以select*一个新表，然后在？

问题1:因为Flink CDC源表不是不能定义watermark嘛，那我可以select*一个新表，然后在新表上定义watermark从而开窗聚合吗？这样可以将流处理变为批处理。不知我的想法可不可行？问题2:emmm应该是吧(flink理解的不是很深)，不知道这可行吗，我是用这个来算数据(捕获到数据包的时间戳)开窗聚合1s，因为得用jion来获取前面一列的数据。所以我觉得如果改为water.....

请问，flink cdc 全量同步不加锁，如果要同步binlog之前的数据的话，是通过select 查表获取全量数据的吗？另外：在同步全量数据的同时，如果数据库还有更新，那么是如何解决的？

flink cdc oracle 建了某张表的映射，执行 select * from table,在oracle查看是建了4个连接，关闭select * 后，oracle还能查看到两个连接，这是为什么呢，有大佬知道吗？一个任务两个连接一直没关闭，随着任务的增多，未能正常关闭的连接也增多，导致连接数满了，这种情况咋处理？

请教下flink cdc在sql里面如果有复杂select嵌套，遇到DELETE的binlog时，会如何处理，会将select出来的数据转成delete，还是会变为更新数据？
