Paper Abstract

The Engineering Data Processing (EDP) component of the James Webb Telescope (JWST) Data Management System (DMS) will collect calibrated engineering values for about 15,000 parameters, 300 million samples per day, with a potential daily database growth of 14 GB, 5 TB per year, 50 TB for a 10-year mission. While data will be mostly received in (time, parameter) order, fast access requires translation into (parameter, time) organization and sorting. Organization and indexing of the data will affect storage requirements as well as ingest and access efficiency. Fast access is critical to pipelines processing and calibrating science data.
