Implement Actor Model pattern #3232
Description
Description
The Actor Model is a concurrency paradigm in which independent “actors” encapsulate state and behavior, interacting solely through asynchronous message passing. This approach avoids shared mutable state and promotes highly scalable, loosely coupled systems. Actors can create new actors, send messages to other actors, and handle messages they receive.
Key Elements
- Actors: Independent units that manage their own state and process messages.
- Message Passing: Non-blocking communication between actors; no direct method calls or shared variables.
- Isolation: Each actor’s state is private, limiting concurrency issues.
- Supervision: Some actor frameworks use a hierarchy where parent actors supervise the lifecycle and errors of child actors.

Acceptance Criteria
- Create a new module or package named
actor-model(or similar). - Provide a minimal actor-based system where multiple actors exchange messages to accomplish a task.
- Demonstrate key concepts: actor creation, message handling, isolation of state, and error handling or supervision.
- Include a README (
.mdfile) explaining the pattern, including code walkthrough and any relevant diagrams. - Write tests verifying actor interactions, ensuring correct behavior under concurrent loads.
- Pass all repository checks (style conventions, CI build/tests).

I'd like to work on this. Planning to use Java's concurrency tools for a basic actor system.

✅ Implementation Completed
Implemented the Actor Model pattern with automatic actor ID and loose-coupling message communication.
Added unit tests for all key classes and verified actual message passing logic.
Increased code coverage to 93.9% (from 45.5%).
Fixed Spotless formatting violations.
Build & tests pass locally via mvn clean install and mvn test.
Quality Gate passed on SonarCloud.
Please review the PR when you get a chance. I'm happy to make further adjustments if needed!

✅ Requested Changes Implemented
Refactored logging using Lombok’s @slf4j annotation
Implemented proper message-passing verification in the unit test (ActorModelTest)
Finalized and committed a fully structured README.md following the project format:
Includes real-world example, diagrams, benefits/trade-offs, usage, etc.
Added working links to references, tutorials, and related patterns
🔁 Kindly review the updates and let me know if any additional changes are needed. Happy to iterate further if required!
