Weighted Load Balancer
Weighted mode for Load Balancer EIP. With this policy in case of failures, the exchange will be tried on the next endpoint.
Options
The Weighted Load Balancer eip supports 0 options, which are listed below.
Name | Description | Default | Type |
---|---|---|---|
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 , (comma). | , | String |
roundRobin | To enable round robin mode. By default the weighted distribution mode is used. The default value is false. | false | Boolean |
Examples
In this example, we want to send the most message to the first endpoint, then the second, and only a few to the last.
The distribution ratio is 7 = 4 + 2 + 1
. This means that for every seventh message then 4 goes to the first, 2 for the second, and 1 for the last.
