Lynx Framework Architecture

Layered Runtime Architecture (v1.2.3)

Lynx Framework v1.2.3 adopts a sophisticated four-layer runtime architecture designed for enterprise-grade microservices:

🏗️ Architecture Layers

1. Application Layer - LynxApp, Boot, Control Plane
2. Plugin Management Layer - PluginManager, TypedPluginManager, PluginFactory
3. Runtime Layer - Runtime interface, TypedRuntimePlugin, SimpleRuntime
4. Resource Management Layer - Private/Shared Resources, Resource Info

🔧 Key Architecture Features

Type-Safe Resource Management

• Private Resources: Independent namespace for each plugin
• Shared Resources: Global resources accessible by all plugins
• Generic Access: Type-safe resource access with GetTypedResource[T]
• Resource Tracking: Complete resource lifecycle management

Unified Event System

• Event Bus Manager: Manages inter-plugin communication
• Event Isolation: Plugin namespace prevents conflicts
• High Performance: Supports 1M+ events/second
• Observability: Event filtering, history, and monitoring

Plugin Lifecycle Management

• Hot-Plugging: Zero-downtime plugin updates
• Dependency Injection: Automatic resource wiring
• Health Monitoring: Per-plugin health status
• Error Recovery: Circuit breaker with automated recovery

Production-Ready Monitoring

• 52+ Prometheus Metrics: Standardized lynx_ prefix
• Grafana Dashboards: Multi-panel views for each plugin
• Health Endpoints: /health, /ready for Kubernetes
• Distributed Tracing: OpenTelemetry integration

🚀 Performance Characteristics

Component	Throughput	Latency	Improvement
Redis Operations	162K+ ops/sec	less than 1ms	+15%
RabbitMQ Messages	175K+ msg/sec	less than 5ms	+20%
Kafka Messages	30K+ msg/sec	less than 10ms	+10%
HTTP Requests	1.2M req/sec	less than 1ms	+25%
Event Bus	1M+ events/sec	less than 100μs	+30%

The Lynx architecture provides crystal-clear startup and service flow. The plugin mechanism enables flexible extension of microservice capabilities, significantly improving development efficiency and maintainability while maintaining enterprise-grade performance and reliability.
