请问 flink sql CDC 如何实现维表延迟join？

问答 2021-12-07 来自：开发者社区

Flink 维表延迟join是什么回事呢？

大家好，请教一个问题，流表和维表在JOIN时，如果流表的数据没在维表中时，能否进行延迟join，比如，每10分钟进行match一下，连续match6次都没有match上的话，丢弃该数据。这个场景怎么通过flink SQL或UDF实现，目前是通过timer来实现的，感觉有些麻烦。 *来自志愿者整理的flink邮件归档

为什么Flink 维表延迟join？

我么生产环境同样遇到这种问题，因为上有流数据到了，但是维表数据未更新导致丢失部分数据，请问大家现在有好的解决方案去解决Flink SQL 维表延迟Join的问题了吗？有解决方案的小伙伴能分享下嘛？*来自志愿者整理的flink邮件归档

flink sql维表延迟join如何实现？

延迟join主要是为了解决维表数据后于事实表数据到达问题。java代码可以实现，那flink sql这块能否通过sql hint解决呢？有没有示例？*来自志愿者整理的flink邮件归档
