存储队列触发的 Azure Functions 是接收单个消息还是所有消息? [英] Do Azure Functions triggered by storage queue take single message or all messages?

问题描述

如果我创建一个由存储队列消息触发的 Azure 函数...系统会启动多个并行函数以访问队列中的每条消息，还是会调用一个读取所有可用消息的函数?

If I create an Azure Function that is triggered by storage queue messages... will the system launch multiple parallel functions to reach each message from the queue or will a single function get called that reads in all available messages?

简而言之，排队的消息是单独处理还是批量处理?

In short, are queued messages handled individually or in batches?

推荐答案

在 API 方面，您的函数将在队列中的每条单独消息中调用一次.

API-wise your function will be called once per each individual message in the queue.

但 Azure Functions 运行时会批量检索和处理消息，并行调用函数的多个实例.

But Azure Functions runtime will retrieve and process messages in batches, calling several instances of your function in parallel.
