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. Golang support for Azure Functions

    C# and other environments are already supported; it would be nice if Go / Golang was one of them. I'd love to handle web requests using Golang + Azure Functions.

    It could provide the "HTTP Requests" via the stdin, while the "HTTP Response" can be given via the stdout. (or whatever those two are called on Windows ;-) )

  3. Global exception handler

    Make it possible to have a global exception handler in C# Azure Functions App project - to be able to handle exceptions in one central location.

  4. Julia lang support for Azure Functions

    With Julia lang reaching v1.0 last year, it is emerging as a force in machine learning and other scientific computing applications,

    https://juliacomputing.com/case-studies/

    In particular, BlackRock's Aladdin, Conning Asset Management, and Aviva are all using Julia for financial risk modeling and I see a great opportunity for Julia to impact finance among other things. I'd love to be able to use Julia in Azure Functions for my fintech startup.

  5. Support Service Bus trigger with use of SAS token

    In our company we are using Service Bus with a framework that deals out the SAS tokens to queues. These tokens are living for few days only and concern hierarchical queues (eg. queue name could be productA/event-type-B/subtypeC) and only Listen policy.
    This would mean that listening on a different level then root level of namespace would be needed.
    Best if also the whole connection to SB described by this token would be separate object from the Function, so we could modify it (by altering with new SAS token/whole connection string) without modifying the Function code (as API Connections in Logic…

  6. Add C++ support for Azure Functions

    Allow C++ binaries to contains Azure Functions. It could be done by invoking the main in an executable, or a DLL with a specific export method with predefined signature.

    C++ allows to control memory usage and allow users to be incredibly fast when used properly. In an environment where scaling is needed, squeezing a few seconds of CPU or lowering a few KB of RAM can translate to hundreds or thousands of dollars in savings.

    If memory leaks are a concern, putting aside the fact that C# code can also leak, you could create fail safes for Azure Functions. A…

  7. Add support for hybrid connections to Consumption Plan

    Can we add Hybrid Connections to functions running in Consumption Plans

    I'm aware of the idea ...
    https://feedback.azure.com/forums/355860-azure-functions/suggestions/14807298-should-support-hybrid-connections

    But this is for App Service Plans, and only mentions Consumption Plan in the response.

  8. Enable direct internal Function-to-Function calls

    There is a need to call one Function from another Function without an Internet round-trip, and without dependencies on additional services. (To me, "no Internet round-trip" implies the same region, but if "anywhere within Azure" optimizations could be made without a direct http call to go elsewhere, that would also be ideal.)

    Since the request linked below was closed as Completed even though the "resolution" refers to orchestration, a completely different concern, I'm opening this to re-request with the original intent.

  9. Set environment variable override for AuthorizationLevel.Function key

    When running within the Azure Functions Runtime inside of a Docker container, we can't use AuthorizationLevel.Function as there is no way to retrieve the key from the runtime. It'd be great if we could directly set a function key in our compose.yml as an environment variable. For deployment, we just leave the environment variable blank and the App Service can set the keys.

  10. Support for queue settings per function

    As I was looking for a way to configure the visibility timeout for queue messages I found that the only configuration seemed to be at the host level. The problem is that my queues have different needs and one setting will not work optimally for all queues. I am looking for a way to configure each queue independently.

  11. Add support to Open Tracing/Zipkin

    Opentracing (http://opentracing.io/) is a popular standard for tracing correlated requests across many different services communicating via RPC. It contains implementations on several different platforms and various tools (zipkin being one of the most popular ones). The standard can be easily extended over HTTP using dedicated headers from client/server side. It would be great if Azure functions would be able to provide more or less transparent support for it.

    We are currently working on supporting a suite of Azure based distributed tracing solutions. We have no current plans to support this tool, but would love to hear from the community, and are leaving this item open to collect feedback :)

  12. Manage Function Proxies using the Azure REST API

    Similar to how functions work, it would be useful if we can programmatically manage Proxies within Functions using the Azure REST API.

  13. Support for blob trigger on entire storage account

    Microsoft’s mobile services are designed to place blobs that are pushed in from mobile clients into many containers - a separate container for each entity that the files are associated with. Microsoft’s solution for sourcing events from blob operations is not compatible with this, as the existing blob trigger required you to know the name of the container at setup/binding time. It would be useful to have a blob trigger that can monitor an entire storage account.

    Changing this and clarifying. You can do this today with the Event Grid trigger (e.g. create an event grid trigger and then add subscriptions for each container in a storage account – or many storage accounts – and point to same function). That’s the way that works today and is planned to be the solution for this short term. However leaving this open as I think it was more general to have the Blob and not the Event Grid trigger do this. Keep the votes coming and comment on if Event Grid may not be enough.

  14. Quartz Timer Feature

    Please enhance Azure Functions or Azure in general that exposes an API against which we can post quartz like timer jobs.

    Would be great to set a timer in Azure that can eventually trigger an Azure Function when executing.

  15. Renaming functions using the web UI

    Renaming an Azure function doesn’t seem to be easily possible using the web interface. It would be helpful if the user could:
    - right-click the function name and choose a rename option in a context menu
    - use the “Manage” submenu (which already allows to delete a function)

  17. Scala support for Azure Functions

    The Java worker for Functions allows Scala to be exectured in Functions relatively easily. It would be great to see Microsoft support Scala as they do Java with MSFT endorced build and deploy practices.

  18. Provide memory usage data in context object

  19. When publishing through Visual Studio, create the storage account on the same region as the function

    I deployed my function through Visual Studio, creating a new one on an existing resource group.

    I chose to create a new Storage Account as well.

    I chose eastus2 as the region for my function. But after the deployment succeeded, I noticed that the region for the storage I created during the functions deployment was set for Central US.

    I'd like the created storage to be on the same region of the function. I double checked and there's no way to select a region for the storage you create in deployment time.

  20. local settings json

    Add the ability to create a template local.settings.json file in the dev tooling for VSCode and Visual Studio. Since local.settings is git-ignored by default, when a developer clones down a repo they often have to re-create a local.settings.json file. To do this it involves simply creating a bare json file and hand-coding the right schema/values. It would improve developer productivity to add a "New local settings file..." option to the dev tooling which creates the same skeleton file a dev is given in a new function project.
