请问各位大佬，flink-cdc 做regular join state设置永不过期会有问题，但是

请问各位大佬，flink-cdc 做regular join state设置永不过期会有问题，但是我们的业务场景需要state内保存全量数据，有什么其他解决方案吗？(业务场景无法做 interval join ) 我们目前是通过flink-kafka 处理，定时向kafka内同步历史数据，从而保证flink内一直有全量数据；但是定时同步会有短时间的反压问题。

flink的state过期设置

想咨询一下关于state的ttl问题; 想问一下 state设置的ttl,如果从checkpoints重启 ttl会不会失效；ttl针对的是process time，比如我设置的7天过期,重新从checkpoints启动是第一次启动的时间算还是恢复时的新processtime算；他是state的一部分还是怎么算；或者要注册定时器来实现 *来自志愿者整理的flink邮件归档
