AB - The data logging system for SPring-8 was upgraded to the new system using NoSQL database, as a part of a MADOCA II framework. It has been collecting all the log data required for accelerator control without any trouble since the upgrade. In the past, the system powered by a relational database management system (RDBMS) had been operating since 1997. It had grown with the development of accelerators. However, the system with RDBMS became difficult to handle new requirements like variable length data storage, data mining from large volume data and fast data acquisition. New software technologies gave solution for the problems. In the new system, we adopted two NoSQL databases, Apache Cassandra and Redis, for data storage. Apache Cassandra is utilized for perpetual archive. It is a scalable and highly available column oriented database suitable for time series data. Redis is used for the real time data cache because of a very fast in-memory key-value store. Data acquisition part of the new system was also built based on ZeroMQ message packed by MessagePack. The operation of the new system started in January 2015 after the long term evaluation over one year.
