设置当前会话（Session）的DML是否在日志节点（Change Data Capture,CDC）生成Binlog

sql_log_bin变量可以控制当前会话（Session）的DML在日志节点（Change Data Capture，CDC）是否会生成Binlog，默认情况下允许生成Binlog。批量更新或插入数据时会大量生成Binlog，会对Binlog生成和下游消费端的性能产生较大影响。若实际业务中不需要CDC产生的DML Binlog，可以通过sql_log_bin关闭生成Binlog。

Flink CDC的工作原理是通过监听数据库的变更事件

Flink CDC的工作原理是通过监听数据库的变更事件，然后将这些变更事件应用到视图（View）上，从而实现数据的同步。如果你的视图被优化拆分为两个部分，那么Flink CDC需要分别对这两个部分进行同步。在Flink中，视图（View）是一个虚拟表，它基于其他表的查询...

Flink CDC如果我只要针对某个数据库，解析cdc的事件，然后同步到目标库吗？

Flink CDC如果我只要针对某个数据库，开发一个不那么通用的同步工具，是不是可以直接参考对应数据库的flink-cdc-connectors，解析cdc的事件，然后同步到目标库？想做个oracle到mongo的，实时同步，不依赖flink啥的？
