Thanks for the update, Akshay. Supporting `map` along with `array` and `struct` in the `DROP COLUMNS` command definitely enhances flexibility for schema evolution in CarbonData. The linked design doc is also helpful for context. Et pour celles qui veulent faire évoluer leur style avec autant de flexibilité, rien ne vaut une robe élégante qui s’adapte à toutes les envies.
