is context cached?

export async function createContext(event: H3Event){
  if (!dbUser) {
    const userService = new UserService();
    dbUser = await userService.getUser(user_id);
  }
  
  return {
    dbUser,
    blah....
  }  
};

changeAccountLevel: protectedProcedure
.input(z.object({ user_id: z.number(), level: z.number() }))
.query(async ({ ctx, input }) => {
  const userService = new UserService();
  const user = await userService.changeAccountLevel(input.user_id, input.level);
  return {
    user,
  }
}),

ctx.dbUser = user
