otter 同步 RDS 到 DRDS 出现拆分键无法更新问题

[PenguinNO1]

你好，已经参考过 https://github.com/alibaba/otter/issues/225，但是没有解决我的问题
麻烦请教一下：
场景如下：
商品和sku表，一比多，因为查询sku经常根据itemId查询，使用DRDS时，我选择了itemId作为拆分键，但是sku表还有个主键id。现在我用otter实现 RDS到DRDS的增量数据同步时出现了问题（binlog解析并合并出来的EventType为U，EventData里面存在拆分键，报无法更新）

具体报错信息如下：
