From Service to Platform- A Ranking System in Go - Konrad Reiche
Learn how to structure a ranking system in Go, covering topics like gRPC, idiomatic code, error handling, cancellations, and more, to build a scalable and maintainable recommendation system.
- Structure your ranking system in stages to make it easier to reason about and maintain
- Use gRPC to implement your service, it helps to make it clear and simple
- Make use of idiomatic Go code to write maintainable code
- Error semantics and cancellations should be considered
- Meta stages are glue that holds ranking pipelines together, making it easier to combine different stages
- Platform design helps to make your API-first approach
- Recommendation system helps users to find content they find compelling, consisting of 3 main steps: candidate generation, scoring, and ranking
- Clear naming and decoupling should be the principle in designing your pipeline
- Use dependency injection framework
- Flexibility in API design and meta-stages comes with a great deal of responsibility
