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...

flink cdc 3.0 整库同步数据，会导致业务数据库正常访问吗？比如被锁定，或者负载变高。

使用Flink同步MySQL到doris数据库中，时间格式异常

当我完成同步时，我发现Doris数据库中的所有时间格式都变为了如此：1970-02-01 11:00:00.000000，在所有时间格式后面追加了一个点和6个零，这是怎样造成的，该如何解决这个问题

Flink CDC3.0这样修改同步的数据库名字可以吗？
