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. 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.

  2. The dynamic tier should never run out of sockets

    If you have too many connections, you can get SocketExceptions. The dynamic tier was meant to stop us from having to think about server instances, but with a connection limit, the dynamic tier is useless and we are back to the standard service plans.

    This is an awesome idea, and we’re exploring a few options to make it a reality.
    However, the 600 connection limit per instance should be enough for most applications if you’re reusing or closing connections. If you truly need 600 open connections you are likely to run into the 10 minute timeout per execution.
    Even after we add this you will still need to be mindful of your connection management.

    Keep the votes coming!

  3. Retrieve function app keys from ARM template

    Make it possible to set/retrieve function app keys via ARM templates.
    This will make it easier to store it in the settings of an other service while rolling out an environment.

  5. Support authentication for Azure Function Core Tools

    Azure Functions has been great, especially the ability to run the Core Tools locally. However, there are often scenarios where you return data depending on the currently authenticated user. This appears to be supported in Azure Functions in Azure now but there are no options within the Core Tools. This would be hugely useful for local development.

  6. Add Open Connection count to Function App

    We are using a Function App for consuming events from an EventHub, to process each event we make 4-5 REST calls and we find that our S3 instances run out of outbound connections resulting in ETIMEDOUT errors. We opened a support case and we are troubleshooting. However to make it easier to debug and to allow us to put alerts in place it would be nice to have the number of open connections available through the Portal and be able to attach alerts..
    We tried to run netstat from Kudu but thisis not permitted (Access Denied)

    Update: Still planned!
    -
    This is something that we have enabled internally, and are in the planning process of highlighting TCP connections for customers in the “Diagnose and Solve problems” tab. However, we do not have an ETA yet.

    Thanks for the feedback!

  7. Don't 'hardcode' the storage account connection string for the storage account that backs azure functions

    Currently each Function App has an application setting string "WEBSITE_CONTENTAZUREFILECONNECTIONSTRING"which is a fixed (=hardcoded) connection string. This breaks when performing key rotation on the connection string and is opaque to diagnose since that setting is automatically setup by the portal UI/wizard.

    Can you instead just store the subscription ID and storage account name and then fetch the latest connection string for the storage account using the management API? This will make sure that the function app survives storage account key rotations

  8. Azure Function - Event Grid Output Binding

    Presently there is only an Azure Service Bus output binding for Azure Functions, there is nothing to pass the output on to another Event Grid Endpoint.

    This would be very useful.

    Kind Regards

  10. 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.

  11. 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…

    I believe in our latest SDK versions you should be able to use connection strings specific to a single queue / listen-only. These connection strings are stored in app settings and can be updated / rolled without having to modify or redeploy the code. Believe this would be sufficient today? Not sure if anything blocking anymore

  12. Add support for Open API (Swagger 3)

    Azure Functions currently supports Open API (Swagger 2) (https://azure.microsoft.com/en-in/updates/announcing-azure-functions-open-api-swagger-support-preview/).

    Now that Open API 3 has been released, it would be helpful if the latest standard could also be supported

  13. Folders for organizing Functions and a TreeView Function List in the Portal

    Already I have a Functions App that is growing larger than works well in the existing Portal interface.

    I would like to suggest adding support for folders (similar to solution folders in Visual Studio) that allow one to organize functions. And then a TreeView for the Function list in the Portal.

    For example I have several processed in my Function App. Each process may have one or more steps that are usually individual Functions. It would be great to put all the related Functions together in a folder.

  15. Add Auth0 to list of identity providers and allow custom URL in 'URL Authorization Rules

    [This is more an AppService issue but there's not forum for that.]

    It's important to me to have the ability to use a custom authentication UI and Auth0 provide this and their own database for user storage. Otherwise I have to roll my own. My users do not have any existing accounts (including email) and so need a simple username / password experience (as horrible this might be for most of us)

    A reasonable list of providers is available but adding Auth0 will open the possibilities up. Auth0 is not only excellent but acts as a proxy to a very…

  16. Better support for SharedAccessSignature for inputs and outputs

    I have a Azure Function with an Azure Table as input, and I was trying to use a SharedAccessSignature in the connection string. I wanted to limit access to a specific table, and provide no access to other Azure storage services. However, when I try to run the function, there are errors saying that no Blob endpoint is configured, no Queue endpoint is configured, etc.

    I would like to have a connection string with only TableEndpoint and a SharedAccessSignature, and support signatures that limit access to a specific table or even a specific subset of a table (partition key range).…

    Would be great to be able to create or change the request BODY dutring request overrides processing like it is possible for headers and the method already. Expressions could override parts of the body, create a body when e.g. overriding a GET to a POST or update body parts / subparts. Even deletion of body or body parts would be usable...

  19. Allow moving from AppServicePlan to Consumption plan (in Azure portal)

    It should be easy to move between hosting plans for Azure functions so we can change this based on the current needs. At the moment, I would like to move away from app service plan for a lot of functions (use consumption plan instead), but in the future, high continous demand might move some back to an app service plan. Changing between the to modes should be as easy as scaling out on an app service plan

    I have read somewhere that there is a problem if a function was created as an app service plan because of missing storage.…

  20. 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.

    Related: https://feedback.azure.com/forums/355860-azure-functions/suggestions/15622413-enable-calling-of-other-functions-via-internal-id
