[GitHub] [spark] cloud-fan edited a comment on pull request #28707: [SPARK-31894][SS] Introduce UnsafeRow format validation for streaming state store

   I think this PR and SPARK-27237 are orthogonal, and we should have both. SPARK-27237 is a bit hard to be merged as it changes the checkpoint. We may need more reviews to see if it's future proof (e.g. when we want to support schema evolution of the state store).
   
   Anyway, this PR covers the cases that people upgrade from Spark 2.x to 3.x, which is necessary even if we have SPARK-27237.
