Active Standby Nodes

An active standby node exists is a node in an Enterprise Mode database that is available to replace any failed node. Unlike permanent Vertica nodes, an standby node does not perform computations or contain data. If a permanent node fails, an active standby node can replace the failed node, after the failed node exceeds the failover time limit. After replacing the failed node, the active standby node contains the projections and performs all calculations of the node it replaced.
