⚡ Reactive Systems with TuskLang Java

"We don't bow to any king" - Reactive Edition

TuskLang Java enables sophisticated reactive systems with built-in support for reactive programming, non-blocking I/O, backpressure handling, and responsive applications. Build systems that are responsive, resilient, elastic, and message-driven.

🎯 Best Practices

1. Reactive Programming

- Use appropriate operators - Handle backpressure properly - Implement error handling - Use schedulers effectively

2. Non-Blocking I/O

- Configure proper buffer sizes - Use connection pooling - Implement timeouts - Monitor connection health

3. Backpressure Handling

- Choose appropriate strategies - Monitor backpressure events - Implement proper buffering - Use flow control

4. Error Handling

- Implement proper error recovery - Use circuit breakers - Monitor error rates - Implement fallback mechanisms

5. Performance

- Use appropriate thread pools - Monitor resource usage - Implement caching - Optimize memory usage

🔧 Troubleshooting

Common Issues

1. Backpressure Problems - Monitor buffer sizes - Check subscriber capacity - Review flow control - Adjust buffer strategies

2. Memory Issues - Monitor heap usage - Check buffer allocation - Review object pooling - Optimize garbage collection

3. Connection Problems - Check connection limits - Monitor connection timeouts - Review keep-alive settings - Verify network configuration

4. Performance Issues - Monitor thread pool usage - Check scheduler configuration - Review operator usage - Optimize data flow
