Subject A question about skew join hint
Date Tue, 05 Nov 2019 01:21:24 GMT


Hi all:
  i saw skewed join hint optimization in  https://docs.azuredatabricks.net/delta/join-performance/skew-join.html.


it  is a great feature to help users to avoid the problem brought from skewed data. My question
1. which version we will have this ? i have not found the feature in the master branch by
key word "+SKEW" 
2. the article is under Documentation -> Delta Lake->  Optimizations->  Optimize
Join Performance -> Skew Join Optimization,
   is this feature  only in delta lake?




Best Regards
Kelly  Zhang
