Abstract

Embodiments of the present disclosure are directed to a database system and methods for storing and replicating data of a primary database. A method for replicating data item may include receiving replication data from a primary database system and replicating the one or more data items of the primary database system in accordance with the replication data. The replication data may include a transaction log including information on transactions processed by the primary database system and database lock data relating to at least one lock on the one or more data items of the primary database system in order to support simultaneous queries to the primary and replication database systems. The method may also include rolling-back the replication data in the at least one replication database system based on the information on transactions processed by the primary database system and the database lock data.
