Documentation suggestion: Explanation of uri_mode: true for a cloud-based MongoDB solution

[Andrew-S-Rosen]

It took me a while to figure out that if I want to use a URI for a MongoDB, I need to set uri_mode: true in the my_launchpad.yaml file. This is a bit inconsistent with how atomate2/jobflow/maggma behave.

I think it would be worthwhile to add some information to the documentation about using the uri_mode: true flag when trying to access a cloud MongoDB system (e.g. MongoDB Atlas). The appropriate spot would be here.

The relevant code is below for context:

fireworks/fireworks/utilities/filepad.py

Lines 73 to 86 in 2cc3b04

	if uri_mode:
	self.connection = MongoClient(host)
	dbname = host.split("/")[-1].split("?")[0] # parse URI to extract dbname
	self.db = self.connection[dbname]
	else:
	self.connection = MongoClient(
	self.host,
	self.port,
	socketTimeoutMS=MONGO_SOCKET_TIMEOUT_MS,
	username=self.username,
	password=self.password,
	authSource=self.authsource,
	**self.mongoclient_kwargs,
	)
