Flink CDC oracle 的 number 类型做主键，这个问题大家遇到没？

Flink CDC oracle 的 number 类型做主键，oracleCDC 可以捕获变更，但是不能解析主键值，导致后面输出源，不能更新，这个问题大家遇到没？

Flink中我想用es比对oracle查找es中比oracle少的主键数据，还有什么好方案吗？

Flink中我想用es比对oracle查找es中比oracle少的主键数据，除了bitmap还有什么好方案吗？

flink cdc oracle 读取不到表完整数据(只读取到1行，行总数：156)，表没有主键没有

flink cdc oracle 读取不到表完整数据(只读取到1行，行总数：156)，表没有主键没有unique，开启了数据库级最小补充日志，表级为补充日志为all ，有大佬知道这什么问题吗？ flink1.15.3、cdc 2.3.0

请问大佬们，flink写入Oracle，遇到相同主键的咋整？或者有啥参数可以覆盖掉相同主键的数据嘞？
