A Ceph S3 Object Data Store for HEP

Data Analysis, Statistics and Probability 2023-11-29 v1 High Energy Physics - Experiment

Abstract

We present a novel data format design that obviates the need for data tiers by storing individual event data products in column objects. The objects are stored and retrieved through Ceph S3 technology, with a layout designed to minimize metadata volume and maximize data processing parallelism. Performance benchmarks of data storage and retrieval are presented.
