摘要： Disclosed in some examples is a method, the method including detecting that an RDMS is recovering from a failure; sending a request for a last committed transaction on a replication component to the replication component; receiving, from the replication component, the last committed transaction which identifies a transaction that was the last committed transaction at a replication component at a time of RDMS failure; determining that a transaction log on the RDMS includes a transaction that had not yet been replicated at the time of RDMS failure which was committed on the transaction log subsequent to the last committed transaction received from the replication component; and based on that determination rolling back the transaction that had not yet been replicated at the time of RDMS failure.

摘要： A method for reliable data synchronization within a network is disclosed. The producer system stories data in a persistent data store and produces one or more data updates. The producer system simultaneously transmits the data updates to a consumer system and initiating storage of the data updates at the producer system. When storage of the data updates at the producer system is complete, the producer system transmits a first acknowledgment to the consumer system. The producer system determines whether a second acknowledgment has been received from the consumer system, wherein the second acknowledgment indicates that the consumer system has successfully stored the data updates at the consumer system. In accordance with a determination that the second acknowledgment has been received from the consumer system, the producer system changes the temporary status of the data updates stored at the producer system to a permanent status.

摘要翻译： 公开了一种在网络内可靠数据同步的方法。 生产者系统将持久性数据存储中的数据进行故事并产生一个或多个数据更新。 生产者系统同时将数据更新传送到消费者系统，并在生产者系统上启动数据更新的存储。 当生产者系统的数据更新的存储完成时，生产者系统向消费者系统发送第一确认。 生产者系统确定是否已经从消费者系统接收到第二确认，其中第二确认指示消费者系统已经在消费者系统上成功存储数据更新。 根据从消费者系统接收到第二确认的确定，生产者系统将存储在生产者系统中的数据更新的临时状态改变为永久状态。
