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 sql join 可以有 state 存储并从 state 恢复数据吗？

有两个表： tableA： key valueA tableB： key valueB 我之前用 flink state 的方式存储 tableA，tableB 的消息过来以后去 query 这个 state 得到 valueA 直接写 flinkSQL 也可以实现这种功能，但这两个表有时间差，任务停止后重新提交会丢失部分 join 的结果。&nb...
