Example 1 with VoltDbMessageFactory

use of org.voltdb.messaging.VoltDbMessageFactory in project voltdb by VoltDB.

the class RealVoltDB method buildClusterMesh.

     * Start the voltcore HostMessenger. This joins the node
     * to the existing cluster. In the non rejoin case, this
     * function will return when the mesh is complete. If
     * rejoining, it will return when the node and agreement
     * site are synched to the existing cluster.
