2 Commits • 2 Features

Feb 1, 2026

February 2026: Delivered end-to-end scheduling capabilities for search-evaluation experiments across two OpenSearch projects, pairing practical documentation with API specifications to enable repeatable, data-driven evaluations and faster adoption by devs and operators. A dedicated documentation page for scheduling regular search evaluation experiments was published with API endpoints, usage instructions, and reviewer-driven polish. In parallel, Scheduling Experiments API specs for the Search Relevance Workbench were defined, enabling create, retrieve, and delete operations, along with versioning and linting improvements. The work enhances developer onboarding, reduces integration time, and strengthens CI readiness through improved styling and documentation quality.

January 2026 monthly summary for opensearch-project/dashboards-search-relevance: Delivered a feature to improve data freshness for the Pointwise Daily Scheduled Runs dashboard by updating the time range to include the most recent run. Specifically, the dashboard "to" time range now uses 'now', enabling near real-time visibility of the latest daily run metrics. This enhancement strengthens decision support for operators and product teams relying on current data. Major bugs fixed: none reported this month; the focus was feature delivery and code quality. Overall impact: improved data accuracy, faster anomaly detection, and better alignment with daily run cadence, driving more timely responses to issues in production and QA monitoring. Technologies/skills demonstrated: dashboard time-range handling, real-time data considerations, and strong collaboration and code-quality practices evidenced by signed-off-by lines and co-authored commits."
