[ISSUE #5214]Fix operator logic (#5215)
* Implement A2A (Agent-to-Agent) protocol with EventMesh publish/subscribe
architecture
This comprehensive implementation introduces a complete A2A protocol for
EventMesh
that enables intelligent multi-agent collaboration through a
publish/subscribe model
instead of traditional point-to-point communication.
## Core Architecture
### 1. EventMesh-Native Publish/Subscribe Model
- A2APublishSubscribeService: Core service leveraging
EventMeshProducer/Consumer
- Anonymous task publishing without knowing specific consumer agents
- Topic-based routing (a2a.tasks.*, a2a.results, a2a.status)
- Integration with EventMesh storage plugins (RocketMQ, Kafka, Pulsar,
Redis)
- CloudEvents 1.0 compliant message format
### 2. Protocol Infrastructure
- A2AProtocolAdaptor: Basic protocol adapter for A2A message processing
- EnhancedA2AProtocolAdaptor: Advanced adapter with protocol delegation
- EnhancedProtocolPluginFactory: High-performance factory with caching
- ProtocolRouter: Intelligent routing with rule-based message forwarding
- ProtocolMetrics: Comprehensive performance monitoring and statistics
### 3. Agent Management & Discovery
- AgentRegistry: Agent discovery and metadata management with heartbeat
monitoring
- Capability-based agent discovery and subscription matching
- Automatic agent lifecycle management and cleanup
- Agent health monitoring with configurable timeouts
### 4. Workflow Orchestration
- CollaborationManager: Multi-agent workflow orchestration using pub/sub
- Task-based workflow execution with dependency management
- Session management for complex multi-step processes
- Fault tolerance with automatic retry and recovery
### 5. Advanced Task Management
- Complete task lifecycle: Request → Message → Processing → Result
- Retry logic with exponential backoff and maximum attempt limits
- Task timeout handling and cancellation support
- Correlation ID tracking for workflow orchestration
- Priority-based task processing with multiple priority levels
## Key Features
### Publish/Subscribe Capabilities
- **Anonymous Publishing**: Publishers don't need to know consumers
- **Capability-Based Routing**: Tasks routed based on required capabilities
- **Automatic Load Balancing**: Multiple agents with same capabilities
share workload
- **Subscription Management**: Agents subscribe to task types they can
handle
### EventMesh Integration
- **Storage Plugin Support**: Persistent message queues via EventMesh
storage
- **Multi-Protocol Transport**: HTTP, gRPC, TCP protocol support
- **Event Streaming**: Real-time event streaming for monitoring
- **CloudEvents Standard**: Full CloudEvents 1.0 specification compliance
### Production Features
- **Fault Tolerance**: Automatic failover and retry mechanisms
- **Metrics & Monitoring**: Comprehensive performance tracking
- **Scalability**: Horizontal scaling through EventMesh topics
- **Observability**: Full visibility into task execution and agent status
## Implementation Components
### Protocol Layer
- EnhancedA2AProtocolAdaptor with protocol delegation
- CloudEvents conversion and message transformation
- Multi-protocol support (HTTP, gRPC, TCP)
### Runtime Services
- A2APublishSubscribeService for core pub/sub operations
- MessageRouter refactored for pub/sub delegation
- A2AMessageHandler for message processing
- A2AProtocolProcessor for protocol-level operations
### Management Services
- AgentRegistry for agent lifecycle management
- CollaborationManager for workflow orchestration
- SubscriptionRegistry for subscription management
- TaskMetricsCollector for performance monitoring
### Examples & Documentation
- Complete data processing pipeline demo
- Publish/subscribe usage examples
- Docker compose setup for testing
- Comprehensive documentation in English and Chinese
## Benefits Over Point-to-Point Model
- **True Horizontal Scalability**: EventMesh topics support unlimited
scaling
- **Fault Tolerance**: Persistent queues with automatic retry and DLQ
- **Complete Decoupling**: Publishers and consumers operate independently
- **Load Distribution**: Automatic load balancing across agent pools
- **EventMesh Ecosystem**: Full integration with EventMesh infrastructure
- **Production Ready**: Enterprise-grade reliability and monitoring
## Usage Example
```java
// Publish task without knowing specific consumers
A2ATaskRequest taskRequest = A2ATaskRequest.builder()
.taskType("data-processing")
.payload(Map.of("data", "user-behavior"))
.requiredCapabilities(List.of("data-processing"))
.priority(A2ATaskPriority.HIGH)
.build();
pubSubService.publishTask(taskRequest);
// Subscribe to task types based on agent capabilities
pubSubService.subscribeToTaskType("agent-001", "data-processing",
List.of("data-processing", "analytics"), taskHandler);
```
This implementation transforms A2A from a simple agent communication
protocol
into a production-ready, EventMesh-native multi-agent orchestration platform
suitable for large-scale distributed AI and automation systems.
