StorageServices | Azure Blob Storage for Unity | Azure library

Background of my question is that I want to write a custom API that receives file upload requests, validates them, generates a SAS token with the required permissions and returns an HTTP 301 to the calling client containing the URI of an Azure Storage Account with all the required query parameters, for example https://mystorage.file.core.windows.net/share/movie.avi?srt=sco&sv=2020-02-10&ss=f&sp=rwdlacup&st=2022-03-02T14:10:19Z&se=2022-03-02T15:10:19Z&sig=ABC=.

The problem is that both, the Blob Storage REST API and the File Storage REST API need required HTTP headers. This in turn would require the client to set those which I want to avoid, in the best case the client only sends a PUT https://myapi.com/upload with some authentication information and gets back an URI which contains all the necessary parameters to upload files.

The alternative is that the client sends his files to https://myapi.com/upload and the API then takes care of uploading the file to the storage account. Given that the files can get large, I want to avoid this additional overhead, upload the files directly to the destination and use the API just as a validator and SAS provider (as in the second part of this graphics).

I'm trying to add a message to my Storage Queue using the REST API provided in this document: https://docs.microsoft.com/en-us/rest/api/storageservices/put-message

Please note that I cannot use the Azure Libraries for this task, there are no Libraries that I know of for Service Now and I'm setting up the test trigger in Python to simulate the REST API calls that would be made from Service Now. In all instances, I receive a 403 error code with no details in the response or the header of the response.

I am trying to Set the meta deta of a directory in Azure File share using Powershell. Rest API Documentation is https://docs.microsoft.com/en-us/rest/api/storageservices/set-directory-metadata If I remove the x-ms-meta-name:value from below code then it works and it deletes the existing metadata but when I try to add it. it gives an authentication error. Error is mentioned at the end of post. Below is the script

I'm new to R. I'm looking for a script to connect to an Azure Table, and I found some useful information in this thread: Connecting to Azure Table Storage in R

However, when I run the script I get an error very similar to the one that the user posting the question had, and I cannot figure out what's wrong.

This is the code I used (credentials have been modified):

I am trying to post a message to an Azure Storage Queue through a Web activity in Azure Data Factory.

I am following the URL format from this documentation page. My URL looks as follows, where 'myaccount' and 'myqueue' are replaced with my details:

https://myaccount.queue.core.windows.net/myqueue/messages?

I am getting a 404 when I try to post a message in the XML Format:

I cannot figure out what to do here. According to the docs https://docs.microsoft.com/en-us/rest/api/storageservices/performing-entity-group-transactions

I send a post request to

I am getting following error while making REST API call to Get Container ACL using Postman :

Does any one have an example of appending data to a file stored in azure datalake from source using Data Factory and the rest API here

Can I use a copy activity with REST dataset on the sink side ?

Bellow is my pipeline, it consists of a copy activity inside a foreach loop. My requirement is : if the file already exists on the sink then append data to the same file. (the copy activity here overwrite the existing file with just the new data)

Sink :

From microsoft docs, it seems that too many versions will affect the speed of listing operations.

Enabling versioning for data that is frequently overwritten may result in increased storage capacity charges and increased latency during listing operations. To mitigate these concerns, store frequently overwritten data in a separate storage account with versioning disabled.

Will creating a new version do a list operation, or lock something?

what SumanthMarigowda-MSFT said may be List Blobs:

include={snapshots,metadata,uncommittedblobs,copy,deleted,tags,versions, deletedwithversions,immutabilitypolicy,legalhold,permissions}

Optional. Specifies one or more datasets to include in the response:

-versions: Version 2019-12-12 and newer. Specifies that Versions of blobs should be included in the enumeration.
