Overview

Investigation develops a robust metadata system for event processing in ATLAS, highlighting challenges in metadata handling.

Key Points

  • Robust in-file metadata is essential for reliable workflows in the ATLAS experiment, especially with increased event numbers.
  • The study presents advancements in metadata handling, particularly in the ROOT framework, to ensure efficiency and parallelism.
  • Improved storage technologies for metadata payload play a crucial role in summarizing content across multiple sources.
  • The High-Luminosity upgrade from the Large Hadron Collider necessitates new assessment approaches for metadata in workflows.
