推荐答案

首先，请eupgrade Debezium，因为0.8.0版本非常老.

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，但是如果您可以在流媒体中暂停一下，那么我建议您1)停止当前的连接器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，使用更新的白名单表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 to1) Stop the current connector2) Start a new connector with whitelisted new table to execute the snapshot on it3) When snapshot is completed then start the original connector with updated whitelist table list

如果您无法承担停机时间，请检查 DBZ-175 中引入的实验方法.a>

If you cannot afford the downtime then please check the experimental approach introduced in DBZ-175
