[GitHub] [arrow-datafusion] alamb commented on issue #7481: Optimize nested unions

   @crepererum actually implemented these two physical optimizations in IOx: https://github.com/influxdata/influxdb_iox/tree/main/iox_query/src/physical_optimizer/union
   
   It is probably a fairly straightforward exercise to copy them (and their tests) into DataFusion
   
   Thus marking this as a good first issue as the code already exists
