大佬 Flink CDC中我的MySQL时区是系统时区UTC而我们服务器时区是CST时区？

问题1:大佬 Flink CDC中我的MySQL时区是系统时区UTC而我们服务器时区是CST时区？问题2:不是我们MySQL是另外一台服务器，在MySQL中select MySQL服务时区为系统时区（也就是UTC），而要写入hudi组件的服务器是另外的一台通过linux查看是CST时区，

老师请教个有关Flink CDC同步MySQL时区的问题，我们MySQL的时区是系统时区，sink？

老师请教个有关Flink CDC同步MySQL时区的问题，我们MySQL的时区是系统时区，sink的服务器时区是东八时区差了8小时，我每次写入都是把对应的字段“-8”小时，有没有什么参数可以设置？是MySQL时区是系统时区UTC而我们服务器时区是CST时区

flink cdc中我想只保留一条消息,再分发给业务系统怎么处理？

部署多个实例,就会监听重复啊。一个集群,部署了多个节点,每个节点都通过 Flink 来监听 Mysql (全库)或者某些表的变化,当Mysql 表变化时,每个实例都收到相同的变更消息我想只保留一条消息,再分发给业务系统。部署多实例,就是想当一个实例重启时,另一个实例可以继续监听。
