高性能交易引擎ZCETE的设计与实现

针对大规模电子交易中存在的数据密集和事务集中引起交易引擎的性能下降问题，结合内存数据库和主动数据库技术，提出并实现了一个高性能交易引擎ZCETE。讨论了ZCETE中采用的主动响应机制、事务调度策略、数据组织方法、故障恢复措施等关键技术。将ZCETE应用于棉花交易，测试结果表明，在不产生事务延迟的条件下，交易事务的处理速率为1970TPS，平均响应时间为0．5ms，可满足大规模电子交易的需要。

The Design and Implementation of High Performance Trade Engine ZCETE

To solve the problem of the worse performance of trade engine in large scale e-trading induced by both data intensive and transaction concentrative, the paper presents and implements a high performance trade engine ZCETE by integrating techniques of main memory resident database with those of active real-time database. Some key techniques adopted by ZCETE are discussed, including event response mechanism, transaction schedule policy, data manipulation method and crash recovery scheme, etc. The test results of applying ZCETE to cotton trade show that it can process transactions in 1970TPS and each is close to 0.5ms in no delay condition, which meets the need of complicated trade transaction processing in large scale e-trading.
