我有一个疑问，Flink CDC是监听数据变化，然后同步给其它机器。如果需求是通过Flink CDC实现一个多主模式，会不会出现死循环的情况。比如： 1. 监听Mysql binlog日志变化，同步给了TiDB 2. 当写入TiDB的时候，TiDB也会写日志，同时CDC也监听到了日志变化 3. 监听到TiDB数据变化，又同步回了Mysql 会出现这个情况吗？那Flink CDC更适合单向同步吗？

Flink CDC在算子合并的时候怎么才能知道已经写入多少条数据，写出了多少数据？

Flink CDC中像这种情况，要怎么样才能保证数据的原始有序性？是不是不能使用keyBy算子？通过

Flink CDC中像这种情况，要怎么样才能保证数据的原始有序性？是不是不能使用keyBy算子？通过windowAll算子的单线程来保证原始的有序性？
