HeartSaVioR edited a comment on issue #24173: [SPARK-27237][SS] Introduce State schema validation among query restart URL: https://github.com/apache/spark/pull/24173#issuecomment-475420490 For now, the verification is done per partition. That sounds really weird because schema should be same across partitions, but if we want to do it only once for all partitions, we should modify code (maybe some interfaces too, and even maybe DSv2?) to let stateful operators report the states with its key/value schema. So this approach is less optimized and less intuitive, but also pretty less intrusive, doesn't touch the current contract and will work well with custom state store providers.
