问题 I know that the Storage Data Movement Library is supposed to be faster when uploading and downloading files to and from blob storage, but I am not seeing the performance benefits of it when compared to Azure SDK v12. I got an average of 37.463 seconds with Azure SDK v12 and 41.863 seconds using Storage Data Movement Library (SDML). Here is the code using SDML: namespace FunctionApp { using Microsoft.AspNetCore.Mvc; using Microsoft.Azure.Storage; using Microsoft.Azure.Storage.Blob; using

问题 I have a list of file names that I need to search on Azure. Right now as a noob I am looping over each blob names and comparing strings but I think there has to be easiest and fast way to get this done. The current solution is making my HTTP response very slow. def ifblob_exists(self, filename): try: container_name = 'xxx' AZURE_KEY = 'xxx' SAS_KEY = 'xxx' ACCOUNT_NAME = 'xxx' block_blob_service = BlockBlobService(account_name= ACCOUNT_NAME, account_key= None, sas_token = SAS_KEY, socket

问题 I want to create an Azure function that deletes files from azure blob storage when last modifed older than 30 days. Can anyone help or have a documentation to do that? 回答1: Assuming your storage account's type is either General Purpose v2 (GPv2) or Blob Storage , you actually don't have to do anything by yourself. Azure Storage can do this for you. You'll use Blob Lifecycle Management and define a policy there to delete blobs if they are older than 30 days and Azure Storage will take care of

问题 We have a file system abstraction that allows us to easily switch between local and cloud (Azure) storage. For reading and writing files we have the following members: Stream OpenRead(); Stream OpenWrite(); Part of our application "bundles" documents into one file. For our local storage provider OpenWrite returns an appendable stream: public Stream OpenWrite() { return new FileStream(fileInfo.FullName, FileMode.Open, FileAccess.ReadWrite, FileShare.ReadWrite, BufferSize, useAsync: true); }

问题 I am looking for a sample or IP for updating a blob's metadata when it is uploaded. All help is appreciated. I have following function: public static void Run([BlobTrigger("types/{name}", Connection = "StorageConnection")]Stream myBlob, string name, ILogger log) { } 回答1: You can use the trigger to get the ICloudBlob instead of the stream. Check the official documentation on blob triggers for Azure Functions. Basically, your code will look something like this: public static void Run(

问题 I'm trying to delete an image in my aucitonImages container, but when I execute the function from postman, I get SharedKeyCredential is not a constructor I've been following the documentation and I think I have everything setup, but I don't see what's different in my code from the docs.
