   Solved with #3329  - I took a guess after @nastra debugged and tried a bunch of things out. By removing the "when" clauses and just working on base column functions I get the setup time down to ~ 1 minute. As for the actual regression in spark? no idea. Someone should check out the codegen between 2.4.5 and 2.4.6 if they really care :)
