A large-scale trading system, subject of the transaction price of streaming data using the transaction price trigger mode, T + 0 trading system (like stocks, futures, precious metals, etc.). The system needs to record a lot of price data, transaction information and order flow and system performance for demanding (sensitivity of milliseconds), it is necessary to avoid logging service has become the bottleneck of the system performance. By measuring the Performance of several general-purpose log (e.g. log4j, logback), and taking into account that they are relatively cumbersome as universal log decided to develop their own logging system, the system functionality and performance required support. After two months on-line system 20 billion daily turnover RMB, up to 44 billion RMB, 4000 T peak turnover / sec. The system is very large, the log system perfectly support the logging service. Change log system includes the following features: dual buffer queue, a variety of brush disk mechanisms, a variety of RollingFile mechanisms, multi-log level, thermal loading, ultra-lightweight, performance guarantees success for daily transaction volume ten billion trading system.
This hands-on course from scratch with everyone to achieve change log system, from which we can learn a lot of design, coding techniques, advanced knowledge, and ultimately the system is a high-performance logging system available, high commercial value. Finally, the course will do performance testing, so that we see the real performance of the system log.
