在使用dinky+flink cdc+hudi,实现数据入湖的过程中发现一个这样的问题，在同步完全量数据之后，将'scan.startup.mode' = 'latest-offset'这个参数切换为initial之后，对源表中的数据删除，flink cdc不能同步删除掉的数据。但是更新一下这个数据就可以删除了，新增数据也可以同步。这是为什么呢

Flink CDC这种情况有办法提高同步的速率让不同分片同步过来的数据都是最近几分钟更新的吗？

Flink CDC中mongodb同步数据，有个集合有多个分片，现在发现不同分片数据量不一样，同步到的数据有部分是刚更新的，有部分是几个小时前更新的。这种情况有办法提高同步的速率让不同分片同步过来的数据都是最近几分钟更新的吗？

Flink CDC同步postgresql不能配置从哪里开始同步吗，我看默认是先把历史数据全读取了？

Flink CDC有没有大佬实现同步到clickhouse的?
