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.

How can we improve Microsoft Azure Functions?

  1. VS 2017 Azure function for powershell.

    Currently I don't see any powershell support within VS 2017 for developing azure function. Any idea when this would occur?

  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. Support for "delete" DocumentDB Change Feed Trigger

    Currently there is support for DocumentDB Change Feeds which only trigger for Insert and Update changes, however there is no way of picking up Delete changes to a collection

    My use case has a real-time web application which relies on these change triggers to update the User Interface through Web Sockets that a change to a document/collection has taken place, at the moment I am having to implement this manually through a delete API call but that does not solve the problem if a document is manually deleted at source (for example).

    A Delete of a document (IMHumbleO) is as…

  5. Add ability to restrict deployment from dev environments

    I recently created a new function app in our team's tenant to handle some custom monitoring. Now that I'm done prototyping it and have it in a workable state, I've created an Azure DevOps build and release to handle publishing the app.

    I need to do this, rather than simply use the CD from git branch option, because I'm using Typescript (currently unsupported), and need to install both node_modules and extensions for the app (because the app won't perform those steps itself based on package.json or extensions.csproj)

    While the pipeline now works, I can't find a way to lock down…

  6. certificate

    Can Azure Functions support SSL certificate for consumption plan?
    I found on https://docs.microsoft.com/en-us/azure/azure-functions/scripts/functions-cli-configure-ssl-certificate that "To bind an SSL certificate, your function app must be created in an App Service plan and not in a consumption plan."

  9. Function inputs with query or path support should be able to make use of query/body parameters

    The documentation for SqlQuery inputs mentions that this capability is not *yet* supported, and points to a GH comment, but I saw no actual feature request so here it is.

    https://docs.microsoft.com/en-us/azure/azure-functions/functions-bindings-cosmosdb-v2#http-trigger-look-up-id-from-route-data-using-sqlquery-c

    "You can pass route data to the SqlQuery parameter as shown, but currently you can't pass query string values." (link to comment https://github.com/Azure/azure-functions-host/issues/2554#issuecomment-392084583)

    Is there any sort of timeline that users can expect this?

    Also, I think the documentation could be improved to explain that the Route Templates are based on ASP.NET routing, which is where the limitation stems from (because route templates in ASP.NET do not encompass…

  10. When the major upgrade to .NET Framework in the future, We want to do integration tests on Function App.

    When the major upgrade to .NET Framework in the future, We want to do integration tests on Function App. It means that We would like to not only Local tests but also integration tests.
    (ex. executing function app from logic app)
    Also, We would like to have an option to upgrade as and when required.

    [background]
    Currently, we can only local test for upcoming upgrade to .NET Framework 4.7.2

  11. EventHub Trigger filtering based on properties

    It would be great to be able to provide a filtering expression in the binding of an eventHubTrigger. Using this I could configure my function to only be invoked for certain events that match the filter. For example, I store a property called "eventType" in the application properties of each event. My function is potentially only interested in events of one or more specific types. Currently I code this logic into the function, which works fine. However, it counts as an unnecessary invocation and increases the cost. Ideally the filtering would take place in the host and not incur a…

    Unsure on this one but marking as unplanned. The filtering would also have to happen at the client to preserve ordering. However even if we did the filtering before the execution it’s still consuming compute so I don’t think it makes sense for it to be “free.” Just because the trigger is doing filtering before execution wouldn’t necessarily negate the price aspect. And since filtering often has some custom parsing / decoding / conditions it’s almost better to do it in code.

  12. Wildcard within path of blob input bindings

    I wish we could specify blob storage input bindings path that included wildcard.

    --- function.json
    {
    "type": "blob",
    "name": "faces",
    "path": "face/profile-{date}-*.png",
    "connection": "AzureWebJobsDashboard",
    "direction": "in"
    }

    Then, I hope to process these as array of Blob objects.

    ---index.js

    module.exports = function (context, myQueueItem) {
    const fileSizeList = context.bindings.faces.map(face => face.size);
    context.log(fileSizeList);
    context.done();
    };

  14. Support international SMTPUTF8 email addresses in Sendgrid output

    It seems like international characters in email addresses are not supported.

    I think SendGrid supports SMTPUTF8, as indicated here: https://sendgrid.com/blog/episode-2-of-the-grid-podcast

    It would be nice if Azure Functions could successfully implement support for this as well.

    When I send email to an address containing 'ø', the SendGrid portal displays the address as containing 'ø' in place of the 'ø', which is a typical ASCII/UTF-8 encoding mismatch. And the message is dropped with Reason 'Invalid'.

  16. Expose StorageClientFactory or QueueProcessorFactory to enable triggering on client-side-encrypted queues

    With WebJobs, a custom StorageClientFactory can set an EncryptionPolicy in the DefaultRequestOptions such that encrypted queue messages are transparently decrypted when triggering a WebJob.

    Alternatively, the EncryptionPolicy can be set on a queue by queue basis using a custom QueueProcessorFactory.

    If these, or a more general way to modify the JobHostConfiguration were provided, then we would be able to store the storage connection string in Azure KeyVault and use client side encryption with Azure Functions apps.

  18. 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",

    },
