During January 2026, David Ellis focused on stabilizing Prometheus query interval handling within the grafana/grafana repository. He addressed a regression by reverting a recent change that had altered the precedence of the Min Step parameter in Prometheus queries, restoring the previous interval calculation logic. This backend fix, implemented in Go and supported by thorough testing, ensured that Grafana dashboards relying on Prometheus data sources continued to display accurate and reliable metrics. David’s disciplined approach included linking his changes to related issues and documenting the rationale in commit history, demonstrating careful version control and a strong focus on regression-oriented debugging.
