Traditional pickling jar Q&A

Hi everyone! I LOVE Korean food, especially kimchi, and for Christmas my father gave me a BIG traditional pickling jar that I’ve been dying to use!
I understand how it works and how to use it but what I DON’T know is how long I’m allowed to keep kimchi in it. Do I use it just to ferment then put everything in the fridge? Can I leave it in the jar until I finish the kimchi?
Google isn’t alot of help (picture for reference)
Happy munchies! -k
