October 2025 (repository: bytedance/deer-flow): Key feature delivered: Stream Processing Performance Enhancements. Implemented batch updates with an anti-shake mechanism to prevent redundant message processing, refactoring pending updates to use a Map and scheduling updates at ~60 updates/second. Added a buffer size limit to stream fetching to prevent memory overflow and ensured proper reader lock release. Major bugs fixed: redundancy from excessive reprocessing mitigated, lock handling hardened, and memory safety improved via buffer controls. Overall impact: higher streaming throughput, more consistent latency, and improved memory safety, enhancing reliability for real-time data workloads. Technologies/skills demonstrated: concurrency patterns, Map-based state management, batch processing, scheduling, memory management, and robust lock handling.
