How would you design a RESTful API to ensure scalability and maintainability?
- Use proper versioning in URIs.
- Expose internal database schemas directly.
- Make all API endpoints accept only XML payloads.
- Avoid using caching mechanisms.
To design a scalable and maintainable RESTful API, proper versioning is crucial. This involves including version information in the URIs of your endpoints. Versioning allows you to make changes to the API while ensuring backward compatibility with existing clients. It also provides a clear path for deprecating and retiring old versions. Exposing internal database schemas directly is considered a poor practice as it tightly couples the API to the database structure, making it difficult to change or optimize the database without affecting clients. Accepting only XML payloads or avoiding caching mechanisms are not inherently related to scalability and maintainability but may be specific technical decisions based on requirements.
