   I am using spark sql to write data, the amount of data is very large, so I 
don't want to sort the data globally, but I didn't find an example of partial 
sorting in the documentation, I want to add it here, thanks!
   
   Sort by definition in spark sql documentation:
   https://spark.apache.org/docs/latest/sql-ref-syntax-qry-select-sortby.html

   The test:
   The first step is to create a table:

   Then query the data by sort by:
