Blob绑定并发 [英] Blob binding concurrency

问题描述

您好

读取/写入blob原子是什么？

我有一个http触发器，我从中读取基于SharePoint的项目changeToken，这个令牌我存储在一个blob中。

我想知道我是否会同时收到多个请求，每个请求是否会等待其他请求与blob一起完成？

解决方案

blob触发器在内部使用队列，因此最大并发函数调用数由
控制
在host.json中排队配置。默认设置将并发限制为24次调用。此限制分别适用于使用blob触发器的每个函数。

Hi

Is reading/writing to/from blob atomic?
I have a http trigger where I read items from SharePoint based on a changeToken, this token I store in a blob.
I wonder if I get multiple requests at the same time will each request wait for the other requests to be done with the blob?

解决方案

The blob trigger uses a queue internally, so the maximum number of concurrent function invocations is controlled by the queues configuration in host.json. The default settings limit concurrency to 24 invocations. This limit applies separately to each function that uses a blob trigger.
