    • Aspects of the subject matter described herein relate to data change ordering in multi-log based replication. In aspects, local seeds are maintained for subtransactions involved in a transaction, where each subtransaction may occur on a different node that hosts one or more database fragments involved in the transaction. When a subtransaction communicates with another subtransaction in a transaction, the subtransaction sends its local seed to the other subtransaction. The receiving subtransaction compares its local seed with the received seed and updates its local seed if the received seed is logically after its local seed. A subtransaction uses a local seed to generate sequence identifiers for changes made by the subtransaction. These identifiers allow data changes of a transaction that are made on multiple nodes to be partially ordered relative to other changes made during the transaction.
    • 本文描述的主题的方面涉及基于多日志的复制中的数据改变排序。 在方面中,维护涉及事务的子事务的局部种子,其中每个子事务可以在承载事务涉及的一个或多个数据库片段的不同节点上发生。 当子事务与事务中的另一个子事务通信时,子事务将其本地种子发送到另一个子事务。 接收的子事务将其本地种子与接收的种子进行比较,如果接收的种子在其本地种子之后是逻辑上的,则更新其本地种子。 子事务使用本地种子为子事务所做的更改生成序列标识符。 这些标识符允许在多个节点上进行的事务的数据更改相对于在事务期间进行的其他更改而被部分排序。
