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 article presents the design of the Belle II conditions database production environment as well as details about the capabilities and performance during both Monte Carlo campaigns and data reprocessing. 000001192 700__ $$aMarko Bracko 000001192 700__ $$aTodd Elsethagen 000001192 700__ $$aKevin Fox 000001192 700__ $$aCarlos Fernando Gamboa 000001192 700__ $$aThomas Kuhr 000001192 700__ $$aMartin Ritter 000001192 8560_ $$flynn.wood@desy.de 000001192 8564_ $$uhttps://docs.belle2.org/record/1192/files/BELLE2-CONF-PROC-2018-021.pdf
