`df.union` can break caching by design, but it was to optimize a special df pattern `df1.union(df2).union(df3).union...`. This PR does make it worse as `df.union` can break caching more. I'm working on a fix to make `df.union` targeting the special df pattern it was designed to optimize. -- This is an automated message from the Apache Git Service.
