mattcasters opened a new issue, #7488:
URL: https://github.com/apache/hop/issues/7488

   ### What would you like to happen?
   
   This new transform merges multiple pre-sorted input streams with different 
schemas into one globally sorted stream with a unified sparse row layout.  
   It can be combined with the Repeat Fields transform to fill in previously 
known values from various data sources, for example when combining data from 
multiple satellites in a data vault context to build an SCD2 table.
   
   See:
