如何解决？

1我也遇到了类似的情况，我在使用 Hive 场景（数据量：一亿以上）向 Doris 传输数据时遇到了问题。我发现问题的原因是当数据量很大时，栅栏消息滞后，导致检查点超时，而检查点超时又导致回滚任务。我认为可以采用类似 Flink 的解决方案，提高栅栏消息的优先级。

启动脚本调整
或者源头为 cdc，能否把每一次的大小修改小一点
https://seatunnel.apache.org/docs/2.3.3/connector-v2/source/MySQL-CDC
snapshot.fetch.size=1024 整数类型
优化的思路：也可以考虑一下，为什么性能这么差？3/s。
后来发现，依然会报错。可见这个没有用。
配置文件
- seatunnel.yaml
可以把这里的检查间隔修改大一些，一个小时？

checkpoint:

这两个单位应该都是 integer，单位毫秒。
所以也不能太大。
可以考虑把时间间隔调整的非常大，然后每天定时用 cron 触发保存 checkpoint?
