MarketPulse has designed an industrial-grade process management system that provides complete service lifecycle management through the daemon_manager module. The system utilizes a double insurance mechanism: on one hand, it prevents repeated startups through PID file locking, and on the other hand, it has built-in heartbeat detection to automatically recover from abnormal interruptions. Key technical specifications include:
- Supports second-by-second status monitoring, real-time display of memory usage and task queue depth
- Elegant stop function ensures uninterrupted analysis tasks
- Resource Limit Module prevents individual tasks from exhausting system resources
Compared with traditional scheduling methods such as crontab, this solution has three major advantages: task state visualization, automatic error retry (maximum 3 times), and resource usage reduction of 40%. Stress tests show that the system can stably handle daily average of 100,000+ news analytics requests on a cloud host with 256MB of RAM, and the average CPU occupancy rate stays below 15%, which is in full compliance with the Reliability requirements for financial-grade applications
