Subject: A question about skew join hint

 

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
