.net - Azure 服务总线主题分区

Question

我正在尝试向一个主题发送消息，该主题是在选中启用重复检测和启用分区选项的情况下创建的。我没有在我的 BrokeredMessage 实例上设置 SessionId 和 PartitionKey 属性。根据this :

If the queue or topic has the QueueDescription.RequiresDuplicateDetection property set to true and the BrokeredMessage.SessionId or BrokeredMessage.PartitionKey properties are not set, then the BrokeredMessage.MessageId property serves as the partition key.

在创建 BrokeredMessage 实例后，其 MessageId 属性会自动初始化，因此我希望分区能够正常工作。但事实并非如此:

Microsoft.Azure.WebJobs.Host.FunctionInvocationException: Exception while executing function: Functions.ProcessQueueMessage2Async ---> System.InvalidOperationException: SessionId needs to be set for all brokered messages to a Partitioned Topic that supports Ordering, Topic Name = dev1-mtapp:Topic:response-topic~255. TrackingId:5fbe5df2-8747-4053-ba79-c29a80e9d1ed_G25_B31, SystemTracker:dev1-mtapp:topic:response-topic~255

我哪里错了？

Answer 1

您应该设置: topicDescription.SupportOrdering = false。 例如:

        if (!this.namespaceManager.TopicExists(topicName))
        {
            TopicDescription topicDescription = new TopicDescription(topicName);
            topicDescription.SupportOrdering = false;
            this.namespaceManager.CreateTopic(topicDescription);
        }
