This puzzle is a spiritual successor to Periodic Dagonals, as they use the same global constraints. I don't think there is any need to solve that one before this, but if you want some practice...

Rules
Standard Sudoku Rules apply
Toroidal Diagonals : Digits cannot repeat on the same positive diagonal; diagonals are periodic, that is they continue on the opposite side when they reach the border.
Killer Cages Cages show the sum of the digits; digits cannot repeat inside a cage
Arrows: Digits along an arrow sum to the digit inside the arrow head
An inequality sign between two cages, point to the smallest digit
The Puzzle
Example
An example of a sudoku obeying the Toroidal Diagonals property is shown below. I have highlighted each periodic diagonal with different colors.Happy solving!

Very nice logic. Took me a bit to figure out how the puzzle should be approached due to the clever ruleset.
