ZeebeClient.newTopologyRequest介绍

[英]Request the current cluster topology. Can be used to inspect which brokers are available at which endpoint and which broker is the leader of which partition.

List<BrokerInfo> brokers = zeebeClient 
.newTopologyRequest() 
.send() 
.join() 
.getBrokers(); 
SocketAddress address = broker.getSocketAddress(); 
List<PartitionInfo> partitions = broker.getPartitions();

[中]请求当前群集拓扑。可用于检查哪些代理在哪个端点可用，以及哪个代理是哪个分区的负责人

List<BrokerInfo> brokers = zeebeClient 
.newTopologyRequest() 
.send() 
.join() 
.getBrokers(); 
SocketAddress address = broker.getSocketAddress(); 
List<PartitionInfo> partitions = broker.getPartitions();
