Reddit Comment System (hierarchical)

Question

For those of you who looked at the Reddit source code, where exactly is the logic, where does it control the hierarchical structure of comments?

I downloaded the code, but could not find the database structure, not to mention where the comments are read and written for comments.

Does the update do a lot of comments if someone answers someone in the middle of a thread?

Answer 1

The class definition for the comment model is in r2 / models / link.py.
