Request cluster topology

This example shows which broker is leader and follower for which partition. This is particularly useful when you run a cluster with multiple Zeebe brokers.

Prerequisites​

Run Zeebe broker with endpoint localhost:26500 (default).

final Topology topology = client.newTopologyRequest().send().join();

System.out.println("Topology:");
topology
    .getBrokers()
    .forEach(
        b -> {
        System.out.println("    " + b.getAddress());
        b.getPartitions()
            .forEach(
                p ->
                    System.out.println(
                        "      " + p.getPartitionId() + " - " + p.getRole()));
        });
