Hello, I've been deploying to serverless framework with apollo-server-lambda for awhile and everything is nice and snappy, I just added Prisma to the project with PrismaClient being added to the apollo server context and it's causing massive latency and what seems like stack overflows. Anyone seeing similar things recently?

Hey Dan 👋 Prisma Client is creating a connection to your database which usually adds a bit of overhead but it shouldn’t cause major latencies or any other issues. Can you maybe share a bit more about your project? Are there maybe lots of requests happening at the same time?

For sure! This is a greenfield project. I have been using prisma in production for awhile in a different project so I'm pretty familiar. It's a federated apollo graphql schema. However, the latency is in just one service below the gateway so it's not the gateway causing the issue. Here is all the code:

import { ApolloServer } from 'apollo-server-lambda';
import { schema } from 'core';

const prisma = new PrismaClient();

export interface Context {
  prisma: PrismaClient;
}

export const createContext = (): Context => {
  return { prisma };
};

const server = new ApolloServer({
  context: createContext(),
  schema,
});

export const serverlessHandler = server.createHandler();

and the serverless file:
