getWeight

public int getWeight()

Description copied from interface: ActiveDatabaseMBean

Returns the relative "weight" of this cluster node. In general, when choosing a node to service read requests, a cluster will favor the node with the highest weight. A weight of 0 is somewhat special, depending on the type of balancer used by the cluster. In most cases, a weight of 0 means that this node will never service read requests unless it is the only node in the cluster.

Specified by:

Returns:

a positive integer

See Also:

ActiveDatabaseMBean.getWeight()

setWeight

public void setWeight(int weight)

Description copied from interface: InactiveDatabaseMBean

Set the weight for this database

Specified by:
