Microservice pattern: Domain-specific protocol

Description:
The Microservices - Domain-Specific Protocol design pattern focuses on defining specialized communication protocols tailored to the specific requirements of each microservice domain. This pattern helps in achieving efficient, reliable, and clear communication between microservices by using domain-specific protocols instead of generic ones.

Main Elements of the Pattern:

1. Domain Isolation: Each microservice has its own specific protocol, reducing cross-domain dependencies and promoting autonomy.
2. Optimized Communication: Tailoring protocols to domain-specific needs enhances performance and reliability.
3. Clear Contracts: Well-defined and explicit communication contracts ensure better understanding and fewer integration issues.
4. Decoupling: This pattern supports loose coupling between microservices, making the system more modular and easier to maintain.
5. Scalability: Custom protocols can be optimized for the specific workload, enhancing the scalability of the microservices architecture.

Acceptance Criteria:

1. Implementation: Develop a set of microservices that use domain-specific protocols for communication.
2. Documentation: Provide comprehensive documentation explaining the design and implementation of the domain-specific protocols.
3. Examples: Include examples demonstrating how the domain-specific protocols improve communication efficiency and clarity.
4. Tests: Write unit and integration tests to ensure the domain-specific protocols function correctly and handle edge cases.
5. Code Review: Ensure the implementation adheres to the project's contribution guidelines and coding standards.

The issue does not name files, entry points, existing examples, or tests. Start by reviewing the repository structure and contribution guidelines, then identify where related microservice patterns are implemented. Done means a scoped domain-specific protocol example with documentation, examples, and unit or integration tests, as requested by the acceptance criteria.
