🎯 Architecture Highlights

Hexagonal Architecture

• Pattern: Ports & Adapters (Alistair Cockburn)
• Status: ✅ Validated as HIGHLY SUITABLE
• Ports: 7 interfaces (3 primary, 4 secondary)
• Adapters: 5 adapters (2 inbound, 3 outbound)
• Core Domain: Fully isolated from infrastructure

Key Design Decisions

1. Virtual Threads for Scalability (Req-Arch-6, Req-NFR-1)

   • 1000 concurrent HTTP endpoints
   • Minimal resource usage
   • Java 21+ feature (JEP 444)

2. Producer-Consumer Pattern (Req-Arch-7)

   • HTTP polling (producer)
   • gRPC transmission (consumer)
   • Circular buffer (300 or 300000 messages)

3. Thread-Safe Collections (Req-Arch-8)

   • ArrayBlockingQueue for buffer
   • ConcurrentHashMap for statistics
   • AtomicLong for counters

4. gRPC Bidirectional Streaming (Req-FR-28)

   • Single persistent connection
   • 4MB batch size (Req-FR-30)
   • Max 1s latency (Req-FR-31)

5. Retry with Linear Backoff (Req-FR-18)

   • HTTP: 5s → 300s (5s increments)
   • gRPC: 5s interval indefinitely

Technology Stack

• Language: Java 25 (OpenJDK 25)
• Build: Maven 3.9+ (fat JAR)
• RPC: gRPC Java 1.60+, Protobuf 3.25+
• Logging: Java Logging API (100MB × 5 files)
• Concurrency: Virtual threads + platform threads
• Testing: JUnit 5, Mockito, WireMock, gRPC Testing

---

🚨 Critical Issues Requiring Resolution

1. Buffer Size Conflict (CRITICAL - Stakeholder Decision Required)

• Req-FR-25: "max 300 messages"
• Config Spec: "max_messages: 300000"
• Impact: 1000x difference affects memory and behavior
• Action: Stakeholder must decide: 300 or 300,000?

2. Duplicate Requirement IDs (Medium Priority)

• Req-FR-25: Appears twice (lines 66, 67)
• Req-NFR-7: Appears twice (lines 100, 117)
• Req-NFR-8: Appears twice (lines 101, 118)
• Req-US-1: Appears three times (lines 126, 127, 128)
• Action: Renumber and clarify duplicates
