Azure 服务总线 SessionId 跨多个主题？

[英]Azure Service Bus SessionId across multiple topics?

ASB's SessionId can be used to guarantee ordering, for example if we have 5 messages which update an order, and 3 consumers running, the consumers won't process multiple messages for that order (SessionId = OrderId) at the same time. ASB 的 SessionId 可用于保证排序，例如，如果我们有 5 条消息更新订单，并且有 3 个消费者在运行，那么消费者不会同时处理该订单的多条消息（SessionId = OrderId）。

But suppose I have 3 topics:但假设我有 3 个主题：

CreateOrder创建订单
UpdateOrder更新顺序
DeleteOrder删除订单

If there are X messages spread across these 3 topics, all with the same SessionId, would the consumers for each topic pay any attention to the SessionId being used by other topics?如果有 X 条消息分布在这 3 个主题中，并且都具有相同的 SessionId，那么每个主题的消费者会注意其他主题正在使用的 SessionId 吗？

As in, if a message were being consumed by a CreateOrder consumer with SessionId=5, would the UpdateOrder consumer wait for this lock to release before picking up one of its own messages with SessionId=5?例如，如果 CreateOrder 消费者正在使用 SessionId=5 的消息，UpdateOrder 消费者是否会等待此锁释放，然后再获取它自己的一条 SessionId=5 的消息？

The sessions of different topics are independent and do not affect each other.不同主题的会话是独立的，互不影响。 In other words, when you receive messages with SessionId=1 in topic1, you also can receive messages with SessionId=2 in topic2.也就是说，当你在topic1中接收到SessionId=1的消息时，你也可以在topic2中接收到SessionId=2的消息。 For more details, please refer to the official document Azure Service Bus message sessions .更多细节请参考官方文档Azure Service Bus message sessions 。
