Flink CDC里oracle上要开启归档日志，否则无法cdc，这个怎么处理？

Flink CDC里oracle上要开启归档日志，否则无法cdc，并且开启这个之后，对实际oracle是有很大性能影响，特别是事务。所以oracle cdc在生产环境是无法使用了，没有实际应用价值，测试玩玩也就可以了。这个问题我很早就在群里提出了flink cdc还存在其他的生产环境问题，其一，一般...

flink cdc 在从Oracle拉取数据的时候造成Oracle归档日志暴涨，是什么原因？

Flink CDC 里oraclecdc开启归档模式才可以cdc，有控制归档日志巨量增加的方法吗？

Flink CDC 里oraclecdc开启归档模式才可以cdc，但是这样就会产生将近3倍的归档日志文件。问一下大佬们有控制归档日志巨量增加的方法吗？

Flink CDC中pg归档日志1.8t会影响cdc同步？现在同步每分钟不到10w太慢了？

Flink CDC中pg归档日志1.8t会影响cdc同步？现在同步每分钟不到10w太慢了？可能日志太大导致磁盘满了，io肯定慢很多

Flink CDC有没有遇到归档日志定时清理导致任务失败的场景哇？

Flink cdc解析的是oracle的redo日志还是归档日志？

Flink CDC问下oracle cdc是只读了在线重做日志还是归档日志也读了？

Flink CDC没有变成最新的id 导致dba讲归档日志删除后重启报错？

Flink CDC中1.同步一段时候后会报快照过久问题，2同步一段时间也启动了checkpoint。但是checkpoint 中的scn还是最初任务启动时的id。没有变成最新的id 导致dba讲归档日志删除后重启报错？
