  11. Hi there:
  12.  
  13. I was wondering whether any commercial database system products actually
  14. support hashed joins. If they do, what kind of hashed functions are widely
  15. adopted? (Simple ones such as (Val mod K) or more complicated ones?) Is
  16. order-preserving hashed function ever used in a DBMS implementation?
  17.  
  18. Any info./pointers/implementation experiences related to the above questions
  19. are appreciated.
