摘要： A replication track is a designated group of transactions that are to be replicated at a destination database in a way that, with respect to any other transaction in the replication track, preserves transactional dependency. Further, transactions in a replication track can be replicated at the destination database without regard to transactional dependency of other transactions in another track. This facilitates concurrent parallel replication of transactions of different tracks. Replicating data in this manner is referred to herein as track replication. An application may request execution of transactions and designate different tracks for transactions.
摘要翻译：复制轨迹是要在目标数据库中复制的指定的一组事务，其方式是相对于复制轨道中的任何其他事务来保留事务依赖关系。此外，可以在目标数据库中复制复制轨道中的事务，而不考虑另一轨道中其他事务的事务依赖关系。这有助于同时并行复制不同轨道的事务。以这种方式复制数据在本文称为轨道复制。应用程序可以请求执行事务并为事务指定不同的轨道。

摘要： A system includes an active node and a standby node and zero or more replica nodes. Each of the nodes includes a database system, such as an in-memory database system. Client updates applied to the active node are written through to the standby node, and the standby node writes the updates through to a primary database and updates the replica nodes. Commit ticket numbers tag entries in transaction logs and are used to facilitate recovery if either of the active node or the standby node fails. Updates applied to the primary database are autorefreshed to the active node and written through by the active node to the standby node which propagates the updates to the replica nodes. Bookmarks are used to track updated records of the primary database and are used to facilitate recovery if either of the active node or the standby node fails.
摘要翻译：系统包括主动节点和备用节点以及零个或多个副本节点。每个节点包括数据库系统，诸如内存中数据库系统。应用于主动节点的客户端更新被写入备用节点，备用节点将更新写入主数据库，并更新副本节点。提交票号在事务日志中标记条目，并且如果活动节点或备用节点中的任一个失败，则用于促进恢复。应用于主数据库的更新将自动刷新到活动节点，并由主动节点写入到将更新传播到副本节点的备用节点。书签用于跟踪主数据库的更新记录，并且如果主动节点或备用节点中的任一个失败，则用于促进恢复。
