I'm looking to use Azure CosmosDB mongoDB API with more than 10GB, so I need a shard key to get unlimited storage. Is there anything I have to do with NodeBB for the shard key?
Also, I couldn't find this anywhere and have no forum experience, but excluding media, how much storage does a moderate forum take up?
