Round-Robin Load Balancing

The round-robin is a straightforward load-balancing solution that just iterates over the set of service instances. While being simple, this solution shares the load among the instances and may be sufficient in many cases.

Dependency

First, you need to add the round-robin load-balancer to your project:

<dependency>
    <groupId>io.smallrye.stork</groupId>
    <artifactId>smallrye-stork-load-balancer-round-robin</artifactId>
    <version>SNAPSHOT</version>
</dependency>

Configuration

For each service expected to use a round-robin selection, configure the load-balancer to be round-robin:

stork.my-service.service-discovery=...
stork.my-service.service-discovery...=...
stork.my-service.load-balancer=round-robin
