Is it ok to handle multiple tasks with a single request?

Question

API

To get data at the front, you need to build an API. Ideally, each action should be processed with a separate request to the server, but we cannot allow more than one request: site traffic is half a million a day.
On the site KhTTP / 2, but the majority of them have KhTTP / 1.
We want to use not Rest, but Graf-Kiel.
Whether it will be normal to issue all the necessary data on one request general?

Answer 1

Firstly, your problem is not in the load, the mother is that your architecture does not allow scaling with such attendance. Shame of you
All data on one request sounds wild - the data should be given in the minimum amount for the functioning of a particular module and only on request.
GraphQL is the cure for tons of REST resources and microservices
