  • Patent number: 9411866
    Abstract: Data replication in a database includes identifying a source database system. The source database includes a main index file and a delta log file. To create a replica, one or more symbolic links to the source database system are generated. The symbolic links identify a path to a physical location of the source database. A replica of the source database is generated based on the symbolic links. The replica includes a copy of the main index file and delta log file. Information associated with the replica and the symbolic links is stored in a recovery log. Replica are provided transparently to most database engine components by re-using partitioning infrastructure. Components “see” replica as tables with a single partition; that partition is a local replica.
