Advancing ATLAS DCS Data Analysis with a Modern Data Platform / Formica, Andrea (Université Paris-Saclay (FR)) ; Canali, Luca (CERN) ; Solis, Michelle Ann (University of Arizona (US)) /ATLAS Collaboration
This paper presents a novel approach to enhance the analysis of ATLAS Detector Control System (DCS) data at CERN. Traditional storage in Oracle databases, optimized for WinCC archiver operations, is challenged by the need for extensive analysis across long timeframes and multiple devices, alongside correlating conditions data.

The ATLAS Event Picking Service and its evolution / ATLAS Collaboration
The EventIndex is the complete catalogue of all ATLAS real and simulated events, keeping the references to all permanent files that contain a given event in any processing stage; its implementation has been substantially revised in advance of LHC Run 3 to be able to scale to the higher production rates.

Deployment and Operation of the ATLAS EventIndex for LHC Run 3 / ATLAS Collaboration
The ATLAS EventIndex is the global catalogue of all ATLAS real and simulated events. During the LHC long shutdown between Run 2 (2015-2018) and Run 3 (2022-2025) all its components were substantially revised and a new system was deployed for the start of Run 3 in Spring 2022. [...]

(US)) ; Roe, Shaun (CERN) /ATLAS Collaboration
The ATLAS experiment is preparing a major change in the conditions data infrastructure in view of Run4 In this presentation we will expose the main motivations for the new design (called CREST for Conditions-REST), the ongoing changes in the DB architecture and present the developments for the deployment of the new system. The main goal is to setup a parallel infrastructure for full scale testing before the end of Run3..

The ATLAS EventIndex: a BigData catalogue for all ATLAS experiment events / Barberis, Dario (Genoa U. ; INFN, Genoa ; LBL, Berkeley) ; Aleksandrov, Igor (Dubna, JINR) ; Alexandrov, Evgeny (Dubna, JINR) ; Baranowski, Zbigniew (CERN) ; Canali, Luca (CERN) ; Cherepanova, Elizaveta (Nikhef, Amsterdam) ; Dimitrov, Gancho (CERN) ; Favareto, Andrea (Genoa U. ; INFN, Genoa ; LBL, Berkeley) ; Casani, Alvaro Fernandez (Valencia U., IFIC) ; Gallas, Elizabeth J. (Oxford U.) et al.
The ATLAS EventIndex system comprises the catalogue of all events collected, processed or generated by the ATLAS experiment at the CERN LHC accelerator, and all associated software tools to collect, store and query this information. ATLAS records several billion particle interactions every year of operation, processes them for analysis and generates even larger simulated data samples; a global catalogue is needed to keep track of the location of each event record and be able to search and retrieve specific events for in-depth investigations.

The ATLAS EventIndex using the HBase/Phoenix storage solution / ATLAS Collaboration
The ATLAS EventIndex provides a global event catalogue and event-level metadata for ATLAS analysis groups and users. The LHC Run 3, starting in 2022, will see increased data-taking and simulation production rates, with which the current infrastructure would still cope but may be stretched to its limits by the end of Run 3.
