azure - Azure 服务总线中消息单元可以支持的最大吞吐量和消息速率是多少

Question

我正在尝试对 azure 服务总线高级层进行成本计算。我找不到以下简单问题的答案

• 单个消息单元可以支持的最大消息速率
• 单个消息单元可以支持的最大吞吐量(数据大小/秒)

Answer 1

服务总线高级消息传递不会以这种方式对消息数量施加限制(除了 1 条消息的最大大小为 1 MB，队列/主题的最大大小为 80 GB)。它的作用更像是一种计算资源。根据指标，您应该决定扩大/缩小规模或使用它具有的自动缩放功能。

There are a number of factors to take into consideration when deciding the number of messaging units for your architecture:

• Start with 1 or 2 messaging units allocated to your namespace.
• Study the CPU usage metrics within the Resource usage metrics for your namespace.
• If CPU usage is below 20%, you might be able to scale down the number of messaging units allocated to your namespace.
• If CPU usage is above 70%, your application will benefit from scaling up the number of messaging units allocated to your namespace.

To learn how to configure a Service Bus namespace to automatically scale (increase or decrease messaging units), see Automatically update messaging units.
