实时计算 Flink版检查任务重启的相关内容

Flink默认先全量再增量同步，全量时会对checkpoint上锁，导致请求检查点时失败，任务重启

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停止前选择了创建一次快照但是检查点失效啦此时会使创建快照失败任务频繁重启么？

Flink停止前选择了创建一次快照但是检查点失效啦此时会使创建快照失败任务频繁重启么？我看了下日志原因是检查点失效。

各位请教一个Flink CDC问题，我的系统现在报这个异步检查点问题，之前任务失败了重启了，就报这？
