PROFILE

Diego Giagio

Diego Giagio contributed to the grafana/grafana-plugin-sdk-go and grafana/grafana repositories by building robust backend features that enhance data querying and plugin communication. He implemented chunked data query support and a dedicated error type for unsupported SQL column types, improving both scalability and user experience when handling large datasets. Diego’s work included designing backend endpoints, refining SQL row handling, and introducing feature flags for controlled experimentation, all while expanding test coverage to ensure reliability. Using Go, SQL, and TypeScript, he focused on backend development, error handling, and feature management, demonstrating a thoughtful approach to maintainability and extensibility in core data paths.

February 2026 (2026-02) — Developer Monthly Summary Key outcomes: - Delivered updates across Grafana SDK and Grafana core, focusing on data querying robustness, backend capabilities, and feature experimentation with controlled rollout. Key features delivered and bugs fixed: - grafana/grafana-plugin-sdk-go - Bug fix: Fix negative rowLimit handling in FrameFromRows and robust SQL row handling. Commit d84ee6b9846885ab8168116ac5ecc70f6e602de3. Added comprehensive tests validating behavior for negative and other limits, improving robustness of SQL row handling. - Feature: Add backend endpoint for chunked data requests. Commit 972b274b60d390baf0d238666acd7509355e975d. Endpoint constant introduced and test support added to validate the new chunked data querying path. - grafana/grafana - Feature: Unified Datasource Querying via Feature Flag. Commit 7072be8d45649094d04845e6be0db83e7923b5b4. Introduced dsAbstractionApp OpenFeature feature flag enabling querying of datasources via unified SQL, allowing experimental features to be toggled on/off for flexible feature management. Overall impact and accomplishments: - Strengthened data query reliability and scalability through a new chunked data endpoint and improved FrameFromRows/SQL handling with added tests. - Enabled controlled experimentation for unified datasource querying via OpenFeature flag, reducing risk while accelerating feature validation. - Expanded test coverage and robustness for core data paths, aligning with quality and reliability goals. Technologies/skills demonstrated: - Go programming, backend API design, and test-driven development. - Data querying and SQL handling resilience, including negative limit edge cases. - OpenFeature feature flags for safe experimental rollouts and feature management. - Endpoint design and test support for backend data paths.
