ArnavBalyan opened a new pull request, #7788:
URL: https://github.com/apache/paimon/pull/7788

   ### Purpose
     - IcebergManifestFile hardcodes contains_nan = false in 
`IcebergPartitionSummary`.
     - This value is used by readers for predicate pruning, hardcoding to false 
causes the files to get skipped that contain NaN matches.
     - Detect NaN via the existing min/max and pass it correctly. Issue only 
emerges for float/double values.
   ### Tests
    - UT
