| |
| Weighted Load Balancer, with this policy in case of failures the exchange will be tried on the next endpoint. |
| |
| == Options |
| |
| // eip options: START |
| The Weighted EIP supports 3 options which are listed below: |
| |
| [width="100%",cols="2,5,^1,2",options="header"] |
| |=== |
| | Name | Description | Default | Type |
| | *roundRobin* | To enable round robin mode. By default the weighted distribution mode is used. The default value is false. | false | Boolean |
| | *distributionRatio* | *Required* The distribution ratio is a delimited String consisting on integer weights separated by delimiters for example 2,3,5. The distributionRatio must match the number of endpoints and/or processors specified in the load balancer list. | | String |
| | *distributionRatioDelimiter* | Delimiter used to specify the distribution ratio. The default value is , | , | String |
| |=== |
| // eip options: END |
| |
| == Examples |
| |
| In this case we are using the header test as correlation expression: |
| |
| [source,java] |
| ---- |
| from("direct:start") |
| .loadBalance() |
| .weighted(false, "4,2,1") |
| .to("seda:x", "seda:y", "seda:z"); |
| ---- |
| |
| In XML you'll have a route like this |
| |
| [source,xml] |
| ---- |
| <from uri="direct:start"/> |
| <loadBalance> |
| <weighted roundRobin="false" distributionRatio="4 2 1"/> |
| <to uri="seda:x"/> |
| <to uri="seda:y"/> |
| <to uri="seda:z"/> |
| </loadBalance> |
| ---- |
