This paper demonstrates improvements in the metadata database for High Luminosity LHC, highlighting new mechanisms for physics parameters and database partitioning.
Key Points
The optimization of the ATLAS metadata database architecture will enhance performance for the High Luminosity LHC.
New mechanisms for propagating physics parameters along the dataset inheritance chain were developed to streamline processes.
The introduction of an automatic scoping mechanism helps utilize database partitioning effectively, ensuring transparency.
These enhancements aim to improve metadata aggregation and cataloging based on 25 years of LHC experience.
