In PR#3276, we found a MACRO usecase which wasn't listed before. Therefore adding this usecase and explainations of it in the doc.
Basically, it would be ok to use
MACROfor a constant if it would be referenced massive times and it would be bad to useFUNCTIONfor it which will bring massive performance overhead since SQLFUNCTIONcan't do inlining.Welcome to Perfetto!
