Re: [I] Comet silently produces wrong results while skipping shuffle [datafusion-comet]

sandugood commented on issue #4774:
URL: https://github.com/apache/datafusion-comet/issues/4774#issuecomment-4875473241

   > cc [@mbutrovich](https://github.com/mbutrovich) opened the new issue. Tested it against all of the available images we have (from 3.5 to 4.1, all of them use iceberg-spark-runtime 1.10.1)
   
   This problem is directly related to Spark's AQE (the `ReuseExchange` or `ReuseSubquery` optimizations).
   Tested this query and several others with `spark.sql.exchange.reuse` set to false and got the same results (though, the speed degraded)
