A large-scale transaction system, the transaction target price is streaming data, and the price is used Trigger transaction method, T+0 trading system (like stocks, futures, precious metals trading, etc.). The system needs to record a large amount of price data, transaction information, and order flow, and the system has extremely high performance requirements (sensitivity of up to milliseconds), so it is necessary to avoid the log service becoming a system performance bottleneck. Through the performance pressure test of several general-purpose logs (such as log4j, logback), and considering that they are relatively bloated as general-purpose logs, it was decided to adopt the log system developed by itself to support the system functions and performance requirements. Two months after the system was launched, the average daily turnover was 20 billion RMB, up to 44 billion RMB, and the peak turnover was 4,000 transactions per second. The system is very large, and the log system perfectly supports the log service. The modified log system includes the following features: double buffer queues, multiple flushing mechanisms, multiple RollingFile mechanisms, multiple log levels, hot loading, ultra-lightweight, guaranteed performance, and successfully used in a trading system with a daily transaction volume of tens of billions.
This course takes you from scratch to implement the log system modification, from which you can learn a lot of design ideas, coding skills, and advanced knowledge points. In the end, the system is a usable high-performance log system. The commercial value is extremely high. At the end of the course, a performance test will be done to let everyone see the real performance of the log system.
