@alamb I've realised we can significantly improve on this code now used in Datafusion: If children/columns of the union are marked as `nullable=false`, we don't need to check them, that should bit significantly faster for sparse unions, not sure it'll help as much on dense unions, but it might improve things a bit. I think I can have a crack at this. -- This is an automated message from the Apache Git Service.
