Flink CDC里我部署的flink-cdc任务抓取全量的mysql数据，checkpoint目前是持久化到oss上，我希望每次重启任务的时候不要从头开始抓取所有的消息。我的想法是在任务里面直接获取oss上最新进度的checkpoint目录，然后通过SavepointRestoreSettings去恢复任务进度，但是不生效。请问是什么情况，或者有没有别的更好解决方案？

Flink CDC里mysql做为CDC源，写入到kafka时报错，无法处理有更新和删除的数据。这个问题怎么解决？除了upsert-kafka连接器，正常的kafka连接器是不支持删除和更新的，而数据库支持增删改，所以才不能写入到kafka。但是如果有数据库写入到kafka的需求，不知道该怎么处理？
