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. 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

    Paul

  2. Support for Azure Managed Service Identities in EventHub (and other) triggers

    In Event Hub, I can add my Function App's MSI as a data reader, but in the function I cannot use trigger bindings to read from the queue without using a SecureAccess Key. We are trying to go password free wherever possible, and Azure has been promoting this course of action, so why do we need secret keys for reading from the queue? It then forces us to create and share a secret key for partner teams to read from our queue, rather than just permissioning them in Event Hub.

  3. Add ability to register Service Bus plugins

    Azure Service Bus .NET Standard client supports plugins registration for incoming and outgoing pipeline customizations. Already existing plugings are:
    - Message ID (to follow message ID conventions or for de-duplication)
    - Attachments (claim check)

    Service Bus customers can implement and plug their own plugins to satisfy encryption requierments and other aspects internal to their business. By allowing plugins registration via trigger configuration API, the code normally distributed with the functions would be reduced to a package reference. This will allow Functions authors focus on the logic and not the miscelanious aspects.

  4. Azure Services/PaaS or E2E-scaffolding for Facebook GraphQL/Relay

    There is something beyond Azure App-Services and Functions; Facebook GraphQL as a service, end-to-end which should in clude a CQRS "back-end" (REDIS...) and API-Mgmt/Monitoring features. Here are some examples: https://www.graph.cool/features/ and https://scaphold.io/... but we leverage Azure, so we are currently developing with graphql in AppServices...

  5. Azure B2C Trigger

    It would be really helpful to be able to have triggers on Azure B2C, for example on new user added take some action etc.

  6. Add binding attribute to control function scaling

    We use azure functions extensively. One of the issues we have is not being able to control individual functions scaling. I am not talking bout the function app here, but the functions themselves.

    Using the new attribute binding system could be a very nice way to set the max number of instances a function can spawn.
    [MaxParallelExecution(5)] or something like that.

    this would make it so that particular function does not scale over 5 instances.

  7. 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();
    };

  8. SMTP Triggers

    Functions are great for building HTTP-based Apis. Our SMS-api supports both HTTP(S) and SMTP(Mail 2 SMS).

    In order to use Functions, we would need to be able to bind one or more email domains to it and use email as triggers

  9. Support non-HTTP Triggers on Premium Plan VNET

    As documented here, non-HTTP triggers are not supported.
    Will this be enabled, and is there an ETA? Thanks.

  10. Bind to QueueTrigger using HostId

    I would like to bind to a queue with a name including the function runtime host name (referenced as HostId in some doc). %AzureFunctionsWebHost__hostid% works when that value is set explicitly, but I cannot access it when the default HostId is used.

  11. Connecting to PostgreSQL Database hosted in Azure (Linux + Python)

    Azure Functions Bindings works with Azure Cosmo DB, but as of now there is no way to create a Function that writes to a PostgreSQL db stored in Azure. Locally, I can just use Psycopg2 in Python to connect, but this isn't possible without creating a custom container with libpq-dev (for pg_config).

  12. Use a more unique query param than "code"

    I ran into an issue with an Oauth redirect because the Oauth provider (Kloudless) was also using the code query param for the Oauth redirect. Since the function required this query param I was not able to get the code sent by Kloudless to get an access token. Therefore, I had to just make the function anonymous, since there is no way for me to have Kloudless send it in the headers( I have no control over that). The query param Azure uses for authentication should not be such a vanilla query param. It should at least be like ms-code…

  13. CosmosDB Output bindings should have an option to prevent overwriting a document that changed while the function was executing.

    Currently if you have an Azure function with CosmosDB input and output bindings (with the intent to process and update a document) there is no way to specify that the document should not be overwritten if it was changed (by another entity) between the time the function was invoked and the time it completes and performs the CosmosDB output binding document update operation. That makes the use of input and output bindings together in a single function pretty much worthless for processing and updating a document. The function should return a 409 Conflict error if the etag on the document…

  14. 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…

  15. MQTT Subscriber trigger support as a first class trigger

    Please add support for listening to MQTT 3.0 and 3.1 servers as a subscriber for a trigger. This would be immensely useful in IoT scenarios.

  16. 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'.
