Azure Functions

Azure Functions is an event driven, compute-on-demand experience that extends the existing Azure application platform with capabilities to implement code triggered by events occurring in other Azure services, SaaS products, and on-premises systems. With Azure Functions, your applications scale based on demand and you pay only for the resources you consume. Azure Functions provides an intuitive, browser-based user interface allowing you to create scheduled or triggered pieces of code implemented in a variety of programming languages.

  1. Specifying a name for a premade function

    If no function is present in a Function App, the “getting started” assistant is shown which allows adding a premade function. However, you can’t specify a name for the resulting function there, which is why you’ll end up with insignificant names such as “HTTPTriggerCSharp1” or “HTTPTriggerJS1”. It would be great if the user could optionally specify a function name in this dialog.

  2. Visual Studio Tooling - Javascript Project Template

    C# Project Template was recently added for Visual Studio Tooling https://feedback.azure.com/forums/355860-azure-functions/suggestions/13301214-visual-studios-tooling-with-local-execution-debug , however this doesn't handle all languages - F#, Javascript/Typescript, etc.

    Hoping we can get support added for better deployment capabilities with other languages as well as source code management. Great to see the Azure Function tooling finally make it to RTM for C#!

  3. Scale # of servers in consumption plan based on Service Bus Queue Size

    My service bus will spike at the top of each hour with up to 1000+ messages to get processed immediately. It would be nice for the consumption plan to allow us to scale the # of servers to come online to be based on that queue size. Example: for 1000 messages, I would like 10 servers to come online (1 server per 100 in the queue).

  4. Search input/output bindings

    Want to treat documents of the Azure Search as JSON from the Function Apps.

    First about input bindings. See following pseudo function.json.

    {
    "bindings": [
    {
    "name": "req",
    "type": "httpTrigger",
    "direction": "in"
    },
    {
    "name": "search_result",
    "type": "search",
    "direction": "in",
    "serviceName": "mybookshelf",
    "indexName": "book",
    "apiKey": "envname-SEARCH_ADMIN_KEY",
    "queryType": "full",
    "searchMode": "all",
    "searchFields": ["id", "title", "author"],
    "search": "title:{title} AND genre:{genre}"
    },
    {
    "name": "res",
    "type": "http",
    "direction": "out"
    }
    ]
    }

    When an http request is arrived, contents of $search_result likes as followings.

    [
    {
    "id": "e583e025-01f4-4288-8dec-be6723afe607",
    "title": "Dragon Ball vol.1",
    "author": "Akira TORIYAMA"
    },
    {
    "id": "bb0086f9-e924-450c-b615-f51fb730e339",
    "title": "Dragon Ball vol.2", …

  5. Support etags for Azure Table Storage read/write operations

    I use python functions to read/write into Azure tables, unfortunately the etags are hidden. It would be quite useful to be able to access the eTags to ensure consistency of writes.

  6. local development

    I have had two separate issues where Azure Functions have stopped running in the cloud but work fine on my development machine. One was the extensions.json file not being generated in v1.0.24 of the SDK and another is having to manually add references to the SqlClient package. Neither of which we could replicate locally. Is there a way to ensure that the Azure Functions runtime in VS2019 is the same as what is running in the cloud?

  7. Durable Functions Workflow fixes support

    Workflows on Durable Functions is great until you make some bug in it. And when you do (not "if you do") make a bug, it may result in thousands or even millions of workflows in inappropriate state, or waiting for never-happen events, or just hang in some infinite loop - there are a lot of ways things can go wrong.
    And we need some way to recover the system from those mistakes. Cancellation is one option (AFAIK, it still doesn't support cancelling sub-orchestrators and activities, so not very useful anyway), but workflows sometimes may take days or months to get…

  9. Add option to run function app with Package URL with System Assigned Identity

    Add support to run the function app using system assigned identity with Package URL where the package exists in storage account. so instead of using SAS, it can use System Assigned identity to run the function from package URL

  10. Change log level without redeploy for packaged apps

    Please allow log level to be changed for packaged apps without redeploy.

    Here's my use case and I can't believe I am alone in this... I have an app running at log level Information. There is an issue I want to investigate so I want to increase the log level to Debug or Trace. Because my app is packaged (dotnet if that matters) I can't change the log level without redeploy. That means I have to commit a change to my host.json and rerun my build and deployment pipeline. Adn then back that out afterwards. Because of the need to…

  11. Dynamically disable Queue Trigger Functions

    As of now there is not a good way to dynamically disable a queue triggered function. We have some code running that monitors an endpoint. If that code detects an unhealthy condition, ideally we would like to disable the queue triggered function until the endpoint is ready to accept messages again. I have not seen anywhere to do this outside of manually disabling the function within the portal

  12. Fix issue where CORS breaks Azure functions

    When configuring CORS with multiple/wildcard rules on a storage account any Azure Functions using a storage queue on this account will stop working without any error message.

    I was happy that the support team could provide a workaround on this (use only single CORS rule), but it was a waste of time trying to troubleshoot this crazy flaw.

  16. pandas preinstalled in Python

    Pandas is a de facto standard in small/medium data analysis in Python.

    It might be worth to add a preinstalled version to Python image.

    Saves users time on installation and maybe import pandas will be faster.

  17. Instances with larger memory

    We need to preprocess some large text files - we use pandas and memory usage is well above 100GB. We would need instances with much more than 14GB of memory for that.

  19. PowerShell Az module support

    Hi,

    Will it eventually be possible to manage Azure Functions via PowerShell? Specifically I would like to be able to configure application settings via PowerShell. It seems that only the Azure CLI natively supports this functionality at present https://docs.microsoft.com/en-us/azure/azure-functions/functions-how-to-use-azure-function-app-settings

  20. Enable Log streaming for Azure Functions on Linux

    On Azure Functions on Windows, you can stream the log and see the console output of your app live. This feature does not exist yet in Azure Functions running on Linux but would be extremely helpful for debugging.
