I am no expert on this area. I agree with you that the the test you shared seems to return an unexpected behaviour. I would expect the filter to be correctly applied. Having said that I don't think the issue is coming from the code you have linked on `acero/hash_join_node.cc::CollectFilterColumns`, from my understanding this is the expected behavior. This isn't checking whether there are repeated fields on both schemas, is checking whether the filter field is in both schemas in order to avoid ambiguous filter expressions. cc @zanmato1984 @pitrou which have more knowledge around this and can help understand it better and can validate whether the test is related to a possible bug on right outer join. -- This is an automated message from the Apache Git Service.
