PROFILE
Piotr Bartkiewicz
Piotr Bartkiewicz developed centralized metrics instrumentation for the trinodb/trino repository, focusing on enhancing observability of data exchange operations. He implemented a system in Java that collects and exposes detailed metrics for the FileSystemExchange component, tracking exchanges, sink additions, instance counts, and file or partition size distributions. By exposing these metrics via the Service Provider Interface, Piotr enabled seamless integration with dashboards and alerting systems, supporting performance monitoring and capacity planning. His backend development work consolidated metrics collection with minimal integration overhead, providing foundational support for faster troubleshooting and improved reliability in exchange workloads. The work demonstrated depth in metrics implementation.
