How to make Open edX support multiple mongodb hosts?

I’m trying to set up my edx instance to support multiple mongodb hosts for my module/contentstore.

I’ve seen topics regarding setting up a cluster, but I’m wondering if I can simply add a list of hosts to all my DOC_STORE_CONFIG → host

The idea is that we want to make sure the edx can find the leader mongodb among a few hosts, so we can’t just set one host in the config

If this is not the right way to do it, what’s the correct way?
