Use Case Analysis
When to Use Nerve Framework
- Low-latency requirements - Sub-millisecond response times
- High-throughput scenarios - Thousands of messages per second
- Resource-constrained environments - Minimal memory footprint
- In-process communication - No network overhead
- Real-time applications - Predictable performance
When to Use Traditional Brokers
- Distributed systems - Cross-machine communication
- Persistent messaging - Message durability requirements
- Complex routing - Advanced message routing patterns
- Integration scenarios - Multiple language support
Integration Capabilities
With Traditional Systems
- Bridge Patterns - Connect to external message brokers
- Protocol Adapters - Support multiple communication protocols
- Legacy Integration - Work with existing systems
With Modern Frameworks
- Async/Await Support - Native async/await integration
- Web Framework Integration - Work with web frameworks
- Database Integration - Database connectivity patterns
Conclusion
The Nerve Framework excels in scenarios requiring high-performance, low-latency in-process communication, while traditional message brokers are better suited for distributed systems and persistent messaging requirements.
