摘要： A method and system for processing a transaction request in a distributed data handling architecture. Responsive to receiving a transaction request at a master transaction server, a transaction identifier that identifies a data operation specified by the received transaction request is recorded within a local memory of a replica server. Data operation results are committed master transaction server memory and responsive to committing the data within the master transaction server memory, a post commit signal is sent to the replica server. Data operation results are also committed within local memory of the replica server, and responsive to a failover condition that prevents the master transaction server from sending the post commit signal, the recorded transaction identifier is utilized to synchronize data stored locally within the replica server with data stored within a persistent backend data store shared by the master transaction server and the replica server.
摘要翻译：一种在分布式数据处理架构中处理事务请求的方法和系统。响应于在主交易服务器处接收交易请求，识别由接收到的交易请求指定的数据操作的交易标识符被记录在副本服务器的本地存储器内。数据操作结果是承诺主事务服务器内存，并响应于提交主事务服务器内存中的数据，发送提交信号到副本服务器。数据操作结果也在副本服务器的本地存储器内进行，并且响应于阻止主事务服务器发送后提交信号的故障转移条件，所记录的事务标识符用于将复制服务器本地存储的数据与数据进行同步存储在由主事务服务器和副本服务器共享的持久后端数据存储器中。
