April 2026: Delivered RFC-based cache warmth estimator for vllm-project/semantic-router and integrated it with session transition tracking. The estimator derives cache warmth from TTFT history using percentile anchors and reliability weighting, surfacing warmth in the per-session transition flow to inform routing decisions. Implemented with a narrow latency package API, validated by tests (go test ./pkg/latency). The change is committed under 2596b0a0f9cfd9647fb9d5a1c3eaf3ce5ca2fde1, including a refinement of transition telemetry semantics. This work improves observability, enables cache-aware routing improvements, and provides a foundation for proactive performance optimization across user sessions.

December 2024 monthly work summary focused on delivering public documentation for the Scheduled Query Acceleration (SQA) feature in the opensearch-project/documentation-website repository. The documentation covers concepts, prerequisites, configuration, usage for external data source queries, and best practices for performance and cost management, with troubleshooting steps. This work enables faster onboarding, reduces support overhead, and drives customers toward cost-effective usage of SQA. Major bugs fixed: none reported this month. Overall impact: improved self-service capability and adoption readiness; demonstrated strong technical writing standards and clear traceability for changes.
