punctuation - Comma before which

I'm not sure which of the following sentences is correct. Is the comma mandatory, optional or unnecessary? I've googled a bit about this topic, but I got confused.




Our mapping contains 2000 words, which map to more than one lemma.




or




Our mapping contains 2000 words which map to more than one lemma.





Context: In total, there are more than 2000 words.



I've read Is it appropriate to put a comma before "which"? . If I understand the answers correctly, my "which map to more than one lemma" is a defining clause and no comma is required. But is it wrong to add one?
