摘要
An approach is provided in which a standby component receives a database log record that corresponds to a modification to one of a primary database's corresponding physical storage spaces. The standby component determines whether a modified object associated with the database log record corresponds to a standby database, which includes a replication of a subset of the primary database's corresponding physical storage spaces. When the standby component determines that the modified object corresponds to the standby database, the standby component invokes a physical replay that replicates the modification on the standby database.
