Status of J-PARC operation data archiving using Hadoop and HBase

Kikuzawa, Nobuhiro ; Yoshii, Akinobu; Ikeda, Hiroshi; Kato, Yuko

J-PARC is consists of much equipment. In Linac and 3GeV synchrotron, the data of over the 64,000 EPICS records for these apparatus control is being collected. The data has been being stored by a RDB system using PostgreSQL now, but it is not enough in availability, performance, and extendibility. Therefore, the new system architecture is required, which is rich in the pliability and can respond to the data increasing continuously for years to come. In order to cope with this problem, we considered adoption of the distributed database architecture and constructed the demonstration system using HBase. We present results of these demonstration.
