Proper indoor growing of the stick (pencil) cactus

Question

I am being given a cutting of the stick cactus and I want to grow it indoors and place it on my sunny windowsill. I have read online that in nature, it can grow to tremendous heights. How can I keep it at a reasonable size (height) appropriate for my bedroom? I intend to plant the cutting in a 1-gallon size “Smart Pot” using a cactus succulent potting mix. Any advice that you can give me would be greatly appreciated.
