前言大家好,我是ChinaManor,直译过来就是中国码农的意思,我希望自己能成为国家复兴道路的铺路人,大数据领域的耕耘者,平凡但不甘于平庸的人。今天为大家带来Flink的一个综合应用案例:Flink数据写入Kafka+从Kafka存入Mysql第一部分:写数据到kafka中public stati...

Flink如何消费这些规则数据和kafka的日志流进行关联匹配呢？

配置规则的数据存放在MySQL，这些规则会有增删改的情况，Flink如何消费这些规则数据和kafka的日志流进行关联匹配呢？例如配置规则id=1 ,日志流中有id=1的字段就更新为id=AAA

在Flink我从holo读取数据，数据往kafka 写，好像差12个小时，有没有参数哪里可以配置？

这是因为在Flink中，时间戳默认是以毫秒为单位的，而在HoloDB中，时间戳默认是以纳秒为单位的。因此，需要将HoloDB中的时间戳转换为Flink中使用的毫秒时间戳。你可以通过设置connector.read.format.stringtimeformat参数为yyyy-MM-dd HH:mm:...

在Flink我从holo读取数据，数据往kafka 写，好像差12个小时，有没有参数哪里可以配置？

用flink cdc同步rds上的mysql数据到kafka里，请问这是什么情况？

用flink cdc同步rds上的mysql数据到kafka里，但是每次update的时候会被拆成一个create和一个delete事件。请问这是什么情况，我如果需要update时输出update事件该怎么处理？

Flink CDC想starRocks的物化视图中更新或者新加的数据实时推到kafka这些消息队列？
