Flink CDC会和我们mysql bin log 存储时间有关系吗?

Flink CDC会和我们mysql bin log 存储时间有关系吗?我们同步20个表，有几个表数据有一亿条以上，使用的是 flink-doris-connector 的全表同步方式。全量同步的时候都是一个表一个表同步的。现在全量同步完增量数据没有进来。有没有可能是这段时间mysql bin log换了文件，mysql 服务器的binlog文件本地删除了导致呢

Flink CDC mysql连接器配置这个选项,为啥不同步历史数据呢?

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。
