如题，我是新手小白一个。同步的这个表很大，大概需要4小时时间才能导出所有数据。我在启动一个flink任务时，使用的是1.20版本,对应的flink-sql-connector-oracle-cdc-3.3.0.jar。同步命令如下，默认会先全量同步，对checkpoint上锁，导出这个表的全部数据后创建快照，释放checkpoint锁，接着自动进入增量同步模式：bin/flink run \ .....

Flink CDC里最近遇到一些表无法先全量再增量同步，具体表现就是启动任务后，一直没数据怎么办？

Flink CDC里最近遇到一些表无法先全量再增量同步，具体表现就是启动任务后，一直没数据，目前像这种表，我只能新启动个cdc任务从最新的binglog开始做数据同步，表的历史数据用离线补，有没有大佬知道是什么原因?

Flink CDC增量同步的没问题跑一段时间就会有这个问题任务就挂了？

假使我flink cdc处于增量同步阶段的时候，任务由于某种原因突然间失败了，此时依据配置的自动重？

假使我flink cdc处于增量同步阶段的时候，任务由于某种原因突然间失败了，此时依据配置的自动重启策略重启，是通过检查点标记位置开始读取，还是从initail位置从头读取数据
