Flink CDC中mysql cdc 零点刚过时，大量同步数据，出现部分更新数据丢失的情况怎么办？

Flink CDC中mysql cdc 零点刚过时，大量同步数据，出现部分更新数据丢失的情况吗，具体现象就是30秒左右，同一个数据出现了2次以上的变更，但是下游只更新了一部分，或者干脆没更新。cdc 版本2.2.1,写到doris。变更的字段是非主键字段。

基于 Flink CDC 打造企业级实时数据同步方案

传统的数据集成通常由全量和增量同步两套系统构成，在全量同步完成后，还需要进一步将增量表和全量表进行合并操作，这种架构的组件构成较为复杂，系统维护困难。本方案提供 Flink CDC 技术实现了统一的增量和全量数据的实时集成。
