Description
CERNBox is CERN’s cloud storage and collaboration service, supporting a wide range of physics, general-purpose data and personal files for the CERN community. Despite this broad usage, ROOT files remain a significant part of the platform’s data ecosystem, accounting for a notable share of stored volume and an even larger proportion of read/write activity. Improving the ROOT user experience in CERNBox therefore became a priority for the CERNBox team.
In collaboration with the ROOT Project, we developed a new ROOT file viewer that integrates JSROOT directly into the CERNBox Web interface. The work also led to enhancements in CERNBox’s backend (Reva) including support for HTTP range requests for efficient on-demand loading of large files.
