Subj:   Re: Workaround to avoid product join
 
From:   Victor Sokovin

  sorry for the delay. Thanks a lot for your inputs - I really appreciate. Unfortunately, I must say that the original product join query has the best results in terms of performance among all you proposed and I tried myself.  


Product join has the best performance? I guess we all are learning something new here every day.

A lot depends on the data, of course. Perhaps the pre-aggregation suggested by Dieter did not reduce the volumes much in your particular case? The skew is another thing to check, as always.


Victor
