PROFILE
Rodrigo Pastrana
Rodrigo Pastrana contributed to the hpcc-systems/HPCC-Platform repository by building and optimizing observability, tracing, and reporting features for distributed systems. He engineered automated deployment of observability tooling using Helm and Kubernetes, integrated Elastic Stack with OpenTelemetry Collector, and enhanced trace context propagation across services. Rodrigo improved performance and reliability by refactoring C++ code for health reporting, implementing configuration-driven logging, and strengthening error handling. His work included developing APIs for unified health monitoring, optimizing log processing, and expanding test coverage with unit and integration tests. These efforts resulted in more efficient diagnostics, reduced operational overhead, and greater platform stability at scale.

Jan 1, 2025Monthly performance summary for 2025-01 focused on hpcc-systems/HPCC-Platform. This period delivered two key features with efficiency and observability improvements, fixed performance-related issues, and strengthened monitoring capabilities. The work drives business value through faster, more flexible reporting and enhanced operational visibility, enabling faster decision-making and more reliable performance at scale. Key features delivered: - Zap Report enhancements: Zap Report now handles requests without an explicit timerange by default and generates log queries only when requested, reducing unnecessary log processing and improving reporting efficiency. - OpenTelemetry tracing enhancements and sampling: Exposed new tracing resource attributes (deploymentEnvironment, serviceNamespace) and standardized span naming to improve monitoring readability and consistency. Major bugs fixed: - Prevent LogAccess query when not requested by ZAP, reducing unnecessary queries and resource usage. - Addressed wasteful invalid Span log entries and added JTrace isValid tests to improve tracing reliability and test coverage. Overall impact and accomplishments: - Significant improvements in reporting performance and observability, enabling faster insights and more responsive diagnostics. - Improved resource utilization through smarter sampling and fewer redundant log/span operations, contributing to lower overhead in production. Technologies/skills demonstrated: - OpenTelemetry tracing, resource attributes, span naming conventions, sampling strategies (AlwaysOff, AlwaysOn, Ratio) with parent-based option. - Logging optimization, JTrace integration and validation, and code coverage through tests. - End-to-end feature delivery with measurable impact on performance and reliability.
