推荐答案
首先，请升级 Debezium，因为 0.8.0 版本太旧了.
first of all, pleas eupgrade Debezium as version 0.8.0 is very old.
通常有多种方法可以解决您的问题，但如果您能负担得起流式传输的暂停时间，那么我建议您这样做1) 停止当前连接器2) 使用列入白名单的新表启动新连接器以在其上执行快照3) 快照完成后，使用更新后的白名单列表启动原始连接器
Generally there are multiple approaches to solving your issue but if you can afford a pause in streaming than I'd recommend to 1) Stop the current connector 2) Start a new connector with whitelisted new table to execute the snapshot on it 3) When snapshot is completed then start the original connector with updated whitelist table list
