求大佬解答一下，我现在有个flink cdc任务该怎么处理呢？

求大佬解答一下，我现在有个flink cdc任务，会计算不用的结果列，根据不同属性的列，我分了多个sink table，但是都是写入同一个mysql物理表中，ddl我也定义了主键，应该是开启了upsert的语义的，但是mysql结果表中还是会出现，结果被某些sink 算子直接覆盖了，并没有只是修改对应的列的情况，这种现象需要怎么处理呢？

当mysql源数据过大，要把数据迁移走，便迁移表数据时，又不想影响flink-cdc任务，要怎么办？因为delete的事件也反应在cdc任务中了，这样会导致之前的统计数据也一并被清楚，这种情况该怎么处理？
