Abstract: Read-write splitting technologies have been widely used in the information system of large-scale enterprises. Considering the actuality of core trading system in the traditional telecom operator, this paper applies new technologies, including adding database for reading, data cache and search engine, into the system, in order to find the high performance, high availability, and extensible solution. Experimental results show that the read-write splitting technologies can greatly improve the efficiency of data reading and the overall performance of the system.
