FairCom database replication is an advanced feature allowing high availability and disaster recovery setups across distributed server environments. As replication transfers data from server to server, it is possible to intercept this operation for advanced data transformations. These transformations can include conflict detection and resolution, data transformation, filtering and redirecting data updates, and even replicating to third-party databases. This capability is provided by Replication User-Defined Extensions, an extensive set of callbacks within the Replication Agent process. More than two dozen events can trigger custom callback actions. To learn about Replication Agent state-change events and callback function input parameters, see User-Defined Extensions for Replication.
A tutorial is provided in the document titled User-Defined Extensions for Replication.
