Flink CDC中有没有人遇到过解析binlog 顺序的问题？

在Flink CDC中，有人遇到过解析binlog的顺序问题吗？数据库的binlog顺序是先删除后新增，但CDC解析出来的顺序却是先新增后删除。使用Flink SQL读取MySQL的binlog再写入到Kafka时，不论是在CDC版本2.2.1还是2.4.2，以及Flink版本1.15上都出现了这个问题。就算将Flink的并行度设为1，这个问题仍然偶尔发生，且不是必然出现，另外在GitHub上也....

Flink CDC这个意思是全量阶段也会进行binlog消费吧？

Flink CDC全量结束还是会按照之前的binlog位点进行消费而不是进行合并输出？

Flink CDC全量结束还是会按照之前的binlog位点进行消费而不是进行合并输出？那是不是其他表的binlog也会被阻塞消费呀？

Flink CDC如果有很多binlog，为什么配置上这个，脚本都不同步数据了？

Flink CDC如果有很多binlog，最后指定最近的一个timestamp ，它要从头过滤掉历史Binlog，直到指定的timestamp 才开始同步，我就说，为什么配置上这个，脚本都不同步数据了？

Flink CDC全量历史数据比较多，全量同步阶段时间长会同时读取binlog进行合并输出吧？

Flink CDC全量历史数据比较多，全量同步阶段时间长会同时读取binlog进行合并输出吧，比如新增一张表全量同步耗时三个小时，binlog文件只保留近一个小时的，会影响全量到增量的衔接么，会阻塞其它表的binlog采集么？

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这个参数是指从现在数据库里存在的，最早的一个binlog开始读是吗？

Flink CDC业务库只保留近一个小时的binlog超时间的归档到oss 有啥好的解决方法么？

Flink CDC业务库只保留近一个小时的binlog 超时间的归档到oss 有啥好的解决方法么 cdc有没有接口能读取oss的binlog？
