The COMPASS Event Store in 2002
COMPASS, the fixed-target experiment at CERN studying the structure of the nucleon and spectroscopy, collected over 260 TB during summer 2002 run. All these data, together with reconstructed events information, were put from the beginning in a database infrastructure based on Objectivity/DB and on the hierarchical storage manager CASTOR. The experience in the usage of the database is reviewed a...
متن کاملChronicleDB: A High-Performance Event Store
Reactive security monitoring, self-driving cars, the Internet of Things (IoT) and many other novel applications require systems for both writing events arriving at very high and fluctuating rates to persistent storage as well as supporting analytical ad-hoc queries. As standard database systems are not capable to deliver the required write performance, logbased systems, key-value stores and oth...
متن کاملThe Redesigned BaBar Event Store: Believe the Hype
As the BaBar experiment progresses, it produces new and unforeseen requirements and increasing demands on capacity and feature base. The current system is being utilized well beyond its original design specifications, and has scaled appropriately, maintaining data consistency and durability. The persistent event storage system has remained largely unchanged since the initial implementation, and...
متن کاملThe COMPASS future: COMPASS II
Up to now the COMPASS experiment [1] contributed with the muon beam to precise measurements of the nucleon longitudinal momentum structure. A more complete nucleon description beyond collinear approximation includes the quark intrinsic momentum distributions which are described by the Transverse Momentum Dependent (TMD) Parton Distribution Functions (PDFs) and by Generalised Parton Distribution...
متن کاملEvent Processing over a Distributed JSON Store: Design and Performance
Web applications are increasingly built to target both desktop and mobile users. As a result, modern Web development infrastructure must be able to process large numbers of events (e.g., for location-based features) and support analytics over those events, with applications ranging from banking (e.g., fraud detection) to retail (e.g., just-in-time personalized promotions). We describe a system ...
