The Dynamic Load-balance Endpoint is an endpoint that distributes its messages (load) among application members by evaluating the load-balancing policy and any other relevant parameters. These application members will be discovered using the
membershipHandler class, which generally uses a group communication mechanism to discover the application members. The
class attribute of the
membershipHandler element should be an implementation of
org.apache.synapse.core.LoadBalanceMembershipHandler. You can specify
membershipHandler properties using the
property elements. The
policy attribute of the
dynamicLoadbalance element specifies the load-balancing policy (algorithm) to be used for selecting the next member that will receive the message.
Currently only the
roundRobin policy is supported.
failover attribute determines if the next member should be selected once the currently selected member has failed and defaults to true.
Dynamic Load-balance Endpoint Configuration
Currently the Dynamic Load-balance Endpoint does not support configuring it using a UI. However, you can configure it using its XML source code in the Source View. ClickSource View in the Manage menu under the Service Bus menu of WSO2 ESB Management Console, to configure the the Dynamic Load-balance Endpoint as shown below.
