flink pg cdc 在同步数据库的时候一直会报检查点失败，我看了哈每次都是同样的两个数据库。

我想问一下，pg cdc 在执行检查点的时候是不是要和数据库有关系，比如提交slot 的消费点，我手动改了一下这两个数据库中监控的表，检查点马上就成功了，还有就是检查点执行频繁了对数据库性能有影响没得，如果这个库长时间没有变动，会导致检查点失败，有什么解决办法没得(目前我想到就是定时更新一个表中的某条数据)。下面是我改了数据后的检查点，基本上都是成功。

Flink CDC中pg归档日志1.8t会影响cdc同步？现在同步每分钟不到10w太慢了？

Flink CDC中pg归档日志1.8t会影响cdc同步？现在同步每分钟不到10w太慢了？可能日志太大导致磁盘满了，io肯定慢很多

Flink CDC 无法从检查点处恢复pg同步任务，而是从头对pg数据库又消费了一遍？

Flink CDC 1.13.2、flinkcdc 2.2.1、postgresql 13.82.问题：使用cdc对pg做数据同步时checkpoint可以正常触发保存到hdfs，当任务取消后再从checkpoint进行任务恢复时，无法从检查点处恢复pg同步任务，而是从头对pg数据库又消费了一遍？
