Oct 1, 2025October 2025: Inist-CNRS/lodex delivered two key improvements focused on performance and observability. Preview processing optimization in the enrichment service reduced overhead by removing unnecessary threading and delegating preview command handling, resulting in faster previews and lower resource usage. Enhanced monitoring and metrics collection with koa-prometheus enabled full metrics collection, corrected imports and usage, and removed metrics prefix to align with standard dashboards; improved event marking for access, trace, and errors for better observability. These changes, along with the associated commits, delivered measurable throughput gains and a more maintainable monitoring surface.
