Worked on the open-telemetry/opentelemetry-java-instrumentation repository to modernize benchmarking tooling by updating the Docker image used in benchmark overhead tests from loadimpact/k6 to grafana/k6. This change ensured the benchmarks relied on actively maintained tooling, reducing maintenance risk while preserving the core benchmark logic to avoid regressions. Focused on maintaining the stability and reliability of continuous integration pipelines, the work leveraged Java and Docker, with an emphasis on robust testing practices. No critical bugs were addressed during this period, reflecting the repository’s overall stability. The update improved the reliability of performance metrics and enabled more efficient future iterations.
