Load-Balancing Descriptor Element

2 min read

A load-balancing element determines the load balancing policy used by a replica group.

This element may only appear as a child of a replica-group element.

The following attributes are supported:

Attribute	Description	Required
`load-sample`	Specifies the load sample to use for the adaptive load balancing policy. It can only be defined if `type` is set to `adaptive`. Legal values are `1`, `5` and `15`. If not specified, the load sample default value is `1`.	No
`n-replicas`	Specifies the maximum number of replicas used to compute the endpoints of the replica group. If not specified, the default value is `1`.	No
`type`	Specifies the type of load balancing. Legal values are `adaptive`, `ordered`, `round-robin` and `random`.	Yes

Here is an example to demonstrate the use of this element:

XML

<application name="MyApp">
    <replica-group id="ReplicatedAdapter">
        <load-balancing type="adaptive" load-sample="15" n-replicas="3"/>
        <description>A description of this replica group.</description>
        <object identity="WellKnownObject" .../>
    </replica-group>
    ...
</application>
