Contributed a focused documentation update to the trinodb/trino repository, clarifying the otel.tracing.sampling-ratio configuration property for OpenTelemetry tracing in high-traffic deployments. The work involved aligning documentation with the Airlift OpenTelemetryConfig class to ensure consistency between code and user guidance, reducing ambiguity around trace sampling configuration. Using Markdown and configuration management skills, the update improved the developer experience by providing clear, actionable instructions without introducing code changes, thereby minimizing risk. This effort supported smoother adoption of tracing features, reduced support overhead, and enhanced trace sampling accuracy for large-scale users, demonstrating attention to detail and effective cross-team collaboration in documentation practices.
