A Concise Guide to GraphQL Federation Directives

GraphQL Federation allows you to build a single, unified data graph by combining multiple backend services (subgraphs). The gateway intelligently plans and executes queries across these services. This guide covers the core directives and concepts that make it work.

We'll use a simple e-commerce example with three subgraphs:

• Users Service: Manages user data (id, name).
• Products Service: Manages product data (upc, price, name).
• Reviews Service: Manages reviews, which are linked to users and products.

Of course! Here is a detailed cheatsheet for the advanced parameters shown in your image. I've explained what each one does, when you should adjust it, and what kind of prompts or desired outputs would benefit most from tuning.

LLM Fine-Tuning Parameters Cheatsheet

This cheatsheet helps you understand and tune advanced parameters to control the output of a Large Language Model (LLM). The key is balancing coherence (makes sense, factual, predictable) with creativity (novel, diverse, unexpected).

The twelve-factor app checklist

Also factors in the four principles of modern Release Engineering

• Identifiability Being able to identify all of the source, tools, environment, and other components that make up a particular release.
• Reproducibility The ability to integrate source, third party components, data, and deployment externals of a software system in order to guarantee operational stability.
• Consistency The mission to provide a stable framework for development, deployment, audit, and accountability for software components.
• Agility The ongoing research into what are the repercussions of modern software engineering practices on the productivity in the software cycle, i.e. continuous integration.
