Contributed to the Duansg/hertzbeat repository by developing features that enhance backend reliability and observability. Built a unified global connection cache using the Singleton pattern and LRU caching in Java to centralize collector connection management, improving resource utilization and scalability. Addressed Kafka integration issues by ensuring the AdminClient is recreated when broker lists change, preventing connection errors and increasing system stability. Introduced a JMX Monitoring Factory with extensible interfaces for validator and processor logic, enabling per-application metric collection and flexible system monitoring. Work focused on maintainable, traceable commits and leveraged Java, Kafka, and YAML to support scalable, customizable infrastructure.
