April 2026: Implemented the YDB SQL Driver Issues Handler and User Notifications for the ydb-go-sdk, delivering improved error visibility and proactive issue management. A new context option enables users to receive real-time notifications about issues during query execution, enhancing feedback loops and reducing diagnostic time. This work strengthens the reliability of YDB client integrations and provides clearer guidance for troubleshooting in production. Impact highlights: better error handling, actionable issue signals in client applications, and reduced untracked failures during SQL queries.

March 2026 (2026-03) performance highlights for ydb-platform/ydb: Delivered replication monitoring metrics to improve observability, control, and reliability of replication workflows. Key deliverable is Replication Monitoring Metrics, including replication quoters metrics, throttling counters, and enhanced monitoring/management of replication requests and responses. This work supports proactive issue detection, capacity planning, and SLA adherence. The update is traceable to NBYDB-1942 with commit 62d5fec0e49a3dea0a60f0f531bda8643cb03ad3.

December 2025 focused on improving observability and reliability through a structured-logging refactor across the KQP components. The Structured Logging for KQP Components feature enhances log clarity and traceability, enabling faster debugging and more actionable insights. Delivered in ydb-platform/ydb with a dedicated commit referencing structured logs across executer, session_actor, and node_service. No major bugs fixed this month; the focus was on delivering this significant observability improvement and laying groundwork for future metrics.

For 2025-11, ydb-platform/ydb delivered OpenTelemetry tracing documentation for the YDB Go SDK, with practical code examples for both native Go instrumentation and database/sql usage. This effort enhances observability, accelerates customer adoption of tracing, and aligns the Go SDK with broader OpenTelemetry initiatives. No major bugs fixed this month in this repository. The change is associated with commit b48c4328a3d2a0ad6fb9b97b0dc31d6f155c3131 (#28174).

Monthly summary for 2025-10 focusing on delivering a key observability feature in ydb-platform/ydb-go-sdk. Delivered Contextual Structured Logging Enhancements to the logging package, enabling contextualized log entries through WithFields and FieldsFromContext. The change includes context.go updates, corresponding tests in context_test.go, and a CHANGELOG update. Commit: 2cc902e01c6f6147045530d8724a786e84dd35ed.
