Subject: A question about skew join hint

Hi all:
  i saw skewed join hint optimization in

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
