Flink CDC动态加表，为什么新加的表直接采增量了？有时候新加表从全量开始采，有时候会莫名其妙的一直只采增量。我用了initial也不行，我怀疑是不是和我原本任务的执行模式有关系，我这个采集任务本来是latest的，然后我加完表改成initial，新加的表只采增量，难道和任务最开始的启动模式有关系吗？

Flink CDC中如果一个任务之前只同步两个表，后面加了一个表进去，后面加的会开启快照吗？

Flink CDC被一个taskmanager 对应的表消费，只有一个任务能消费这个数据？

Flink CDC被一个taskmanager 对应的表消费，这个表对应的多个任务只有一个任务能消费这个数据？有没有其他办法呗这个taskmanager下面的所有sql任务都消费呢？

flink sql 如果创建的表有多个sql任务使用这个表，消息只会被一个sql任务消费吗？

flink sql 如果创建的表有多个sql任务使用这个表，消息只会被一个sql任务消费吗？其他任务就没有了？
