Abstract: 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.

Abstract translation: 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。

Abstract: 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.
