Description
The Belle II experiment at KEK is preparing for first collisions in early 2018. Processing the large amounts of data that will be produced requires conditions data to be readily available to systems worldwide in a fast and efficient manner that is straightforward for both the user and maintainer. This was accomplished by relying on industry-standard tools and methods: the conditions database is built as an HTTP REST service using tools such as Swagger for the API interface development, Payara for the Java EE application server, and Squid for the caching proxy. This talk will present the design of the Belle II conditions database production environment as well as go into detail about the capabilities and performance during both Monte Carlo campaigns and data reprocessing.
