Replikationslösungen für PostgreSQL

Die Standard-Installation von PostgreSQL beinhaltet keine Replikationslösung (Stand August 2012). Hierfür gibt es jedoch einige separate und teilweise frei erhältliche Programme:

  • Slony1
    Replication is possible through the „Slony1“ PostgreSQL database replication solution, which is not a part of the core PostgreSQL distribution.
    [http://slony.info/]
     
  • Tungsten Replicator
    Tungsten Replicator is a high performance, open source, data replication engine for MySQL and PostgreSQL.

  • Daffodil Replicator
    Daffodil Replicator is data replication software that synchronizes data residing on corporate backend databases and desktop databases operating in the network. Daffodil Replicator performs data replication based on the ‚Publish and Subscribe‘ model (in client and server architecture). A publication is a collection of one or more tables required for data replication. A subscription is a copy of tables involved in publication on client side.

  • Mammoth PostgreSQL + Replication
    It is designed specifically with reliability in mind and it works with the Open Source and Command Prompt versions of PostgreSQL. Mammoth PostgreSQL + Replication supports asynchronous replication and is designed to be WAN tolerant. It uses a distributed TransactionLog to keep track of updates produced by the Master database. The system allows for multiple Slaves to receive updates in either a continuous or batch mode.
