[GitHub] [spark] ahshahid commented on pull request #29170: [SPARK-30876][SQL] Optimizer fails to infer constraints within join

   I have proposed a PR for the bug SPARK-33152, which proposes a new logic for maintaining constraint propagation which I have seen is able to infer filters / prune filters more rigorously. I think that PR should solve this issue too.
