Developed and integrated Sort Buffer Usage Monitoring for Compaction in the apache/paimon repository, focusing on enhancing observability and performance tuning during heavy workloads. The work introduced new metrics to track maximum, average, and utilization rates of sort buffers, providing actionable insights for resource management and tuning of compaction processes. Implementation centered on Java, leveraging metrics monitoring and performance engineering techniques to instrument core components with a single, traceable commit. This addition enabled more precise tuning of sort-spill-threshold and related options, supporting operational readiness and documentation alignment for performance workflows without addressing bug fixes during the reported period.
