How often?

I've to design APIs, with MongoDB being used as storage.
Will be using Node/ExpressJS for now.

So ... here's my use case.
There would be a lot of attributes/fields in each MongoDB document (more than 20)
But anytime I'd fetch the document, I'd only want 2-3 fields ... based on arguments
Also, there'll be filters passed on to the back-end
Seems like a perfect use case for GraphQL

But the problem is that only a few attributes (~5-6) would be known beforehand.

	# Definition for a binary tree node.
	# class TreeNode:
	# def __init__(self, val=0, left=None, right=None):
	# self.val = val
	# self.left = left
	# self.right = right

	def inorder(root):
	if root.left is not None:
	inorder(root.left)

	const calculate = k => new Promise((resolve, reject) => {
	setTimeout(() => {
	resolve(k**3)
	}, 500)
	})

	const gimme_val = async (k) => {
	transformed_val = await calculate(k)
	return transformed_val
	}

	"foreignField": "airline.name",
	"localField": "airlines",
	"as": "route_docs"
	}
	},
