[GitHub] [beam] kennknowles opened a new issue, #19416: UNION does not work with Double

kennknowles opened a new issue, #19416:
URL: https://github.com/apache/beam/issues/19416

   The SQL operation UNION does not work on numerical columns such as DOUBLE.
   
   The error shown is related to GroupByKey, but I am not sure why UNION includes any steps that require GroupBy which blocks non-deterministic columns.
   
    
   
   Also, would this issue be solved if we implement UNION with a different approach such as BEAM-3721, BEAM-3722 (use flatten instead of CoGroupByKey)?
   
   Imported from Jira [BEAM-7361](https://issues.apache.org/jira/browse/BEAM-7361). Original Jira may contain additional context.
