Question

我有一个ServiceFabric无状态服务，我希望使用EventProcessorHost从特定的EventHub分区中读取。我想从两个事件中心分区映射中读取每个到一个EventProcessorHost

First EventHub Partition =＆gt;第一个EventProcessorHost
第二个EventHub分区=＆gt;第二个EventProcessorHost

  var eventHubClient = EventHubClient.CreateFromConnectionString(serviceBusConnectionString, eventHubName);

            // Get the default Consumer Group
            eventProcessorHost = new EventProcessorHost(Guid.NewGuid().ToString(),
                                                        eventHubClient.Path.ToLower(),                                                            
                                                        consumerGroupName.ToLower(),
                                                        serviceBusConnectionString,
                                                        storageAccountConnectionString)
            {
                PartitionManagerOptions = new PartitionManagerOptions
                {
                    AcquireInterval = TimeSpan.FromSeconds(10), // Default is 10 seconds
                    RenewInterval = TimeSpan.FromSeconds(10), // Default is 10 seconds
                    LeaseInterval = TimeSpan.FromSeconds(30) // Default value is 30 seconds
                }
            };

            ServiceEventSource.Current.Message(RegisteringEventProcessor);
            var eventProcessorOptions = new EventProcessorOptions
            {
                InvokeProcessorAfterReceiveTimeout = true,
                MaxBatchSize = 100,
                PrefetchCount = 100,
                ReceiveTimeOut = TimeSpan.FromSeconds(30),
            };
            eventProcessorOptions.ExceptionReceived += EventProcessorOptions_ExceptionReceived;
            await eventProcessorHost.RegisterEventProcessorFactoryAsync(new EventProcessorFactory<EventProcessor>(deviceActorServiceUri),
                                                                        eventProcessorOptions);

有一个github仓库，它有一个你可以从here构建的实现。它已经维持了很长一段时间，但它似乎可以解决你的问题。

4- Single：将单个事件中心分区映射到单个服务结构分区。 Event Hub通信侦听器将期望提供有效的事件中心分区标识

有没有办法使用EventProcessorHost从特定的EventHub分区中读取
