Flink CDC我指定从mysql-bin.000268的binlog开始同步，为什么还会读？

Flink CDC中mysql-bin.000267是变更了a字段，但我是停掉同步任务的时候做的变更呢，这个时候sink是没变的，然后我指定从mysql-bin.000268的binlog开始同步，为什么还会读mysql-bin.000267？

Flink CDC 实现企业级实时数据同步

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。

Flink CDC没报错，但数据不同步，修改source表数据，sink表没变，为什么？

Flink CDC通过flinksql的方式 flink 1.14.6 cdc 2.4.2 测试souce表以下两种增量同步，都没成功过，'scan.startup.mode' = 'specific-offset','scan.startup.specific-offset.file' = 'mysql-bin.000268','scan.startup.specific-offse...

Flink CDC没办法正常同步数据了，是我姿势不对吗？

Flink CDC没办法正常同步数据了，是我姿势不对吗？mysql 用cdc 2.4.2 souce表用 'scan.startup.mode' = 'latest-offset'可以正常同步数据，但用'scan.startup.mode' = 'timestamp','scan.startup.timestamp-millis' = '1703127600000'

Flink CDC有办法自定义同步到 Sr 的数据库名称吗？

Flink CDC无法创建带减号➖连字符的数据库名， mysql的库名又是这种格式，所以有办法自定义同步到 Sr 的数据库名称吗？
