Which DBMS to choose for storing nested comments?

Question

Database

Good afternoon. I write a comment system on the site. Works on websockets. I use Nodejs on the server. I am writing the system using many examples of writing a simple chat in NodeJS.
But the comments themselves can be nested, and despite this, it is necessary that you can easily search for nested comments.
And also quickly select comments with any indentation (for pagination) with glued child comments.
I considered MongoDB, so in the same chat examples they offer this DBMS.
But I don’t know if it is suitable for my purposes, taking into account the nesting of documents.

Answer 1

Any.

Answer 2

Alternatively, ArangoDB. It supports SQL and can be graph or key-value.
