    This is also related to the N+1 problem, where nested queries make the number of database requests explode. If you want to learn more about this problem, I recommend this video and checking out dataloader, a library released by Facebook to help with batching queries and solving this problem.

    While GraphQL is really promising and helpful, you have to understand that like any technology or framework, it does come with its own set of problems, most of which have already been addressed. For instance you might have heard about the N+1 problem, lack of caching, Query cost and complexity and so on and these have been addressed by some projects like the Dataloader, Persisted Queries, Caching and more which you can setup depending on your needs.

    You might also want to look at how you minimize the amount of calls you make to the main database. Do you need caching and have it setup? Have you addressed the N+1 problem with Dataloader?

    This is where you setup things like batching and also solve N+1 problems with something like a dataloader, setup caching with something like Redis or even an LRU cache to act as a proxy for the frequently accessed data whenever and wherever possible, optimizing the network chatter by using something like persisted queries, optimize your resolvers by retrieving as much data as possible from the parent resolvers, setting up pagination to limit the results returned, setting up things like query complexity to control the level of nesting and computation performed, rate-limiting in the gateway to avoid things like DDOS and so on.
