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： 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.
