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.

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 ;-) )

Enable triggering of Azure functions based on an event in RabbitMQ
Hello, we are having a scenario where we should be able to trigger a function when a message is added to RabbitMQ. This would be really helpful in using Azure functions to integrate with other Message queuing platforms that support AMQP protocol.
107 votesThis now works for Premium plan functions if you enable runtime scale monitoring. We plan to support later in the consumption plan

Allow Key Vault references to access secrets behind Key Vault Firewall
Key Vault references cannot currently be used to access secrets in a vault that has been configured with Key Vault Firewall / service endpoints.
It should be possible to resolve secrets from Vaults configured this way (provided the web app / function app is configured with the right VNET integration).
98 votesWe are still planning to deliver this. Some preliminary work is underway, but we’ll wait to switch to the “Started” status until a few things are further along and we have a better sense of the timeline.

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.

Allow moving Function from Consumption to Service Plan
Currently if you deploy your function on a consumption plan there is no way to move it to an existing Service Plan like any other App Service.
You would need to delete the existing one and redeploy it..49 votesQuick update here – with the announcement of the premium plan we do support moving from consumption to a premium plan. Today this may not work for all consumption apps in a region only because some consumption apps may exist in a “webspace” that doesn’t yet have premium turned on. That said we have CLI commands rolling out in the next few weeks to make this seamless.
Moving to app service plan is a bit trickier as the actual code often lives in a different place on an app service plan (app service local storage) than where consumption needs them (azure storage files) – so moving may not work and currently don’t have any immediate plans to do like “code migration” in addition to changing plans.
You can see a sample of moving plans between apps in this sample here as well: https://github.com/Azure-Samples/functions-csharp-premium-scaler

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…
47 votesThanks for your feedback. Currently, we don’t have any plans for C++ support in Functions. We will monitor the votes on this request to accordingly inform the priority on our backlog.

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.

Apologies on last message – we have started work for controlling checkpoints, not yet for resetting checkpoints. I updated the wrong issue. This is still planned though.

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
34 votesThis makes sense. We are working on solutions to enable storing the secret in Key Vault and account for rotation. There is some additional validation logic that needs to be relaxed to enable these scenarios.

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.
34 votesThis is something we’re looking to enable.

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.32 votesWe do have APIs which make this easier, now. It involves the listKeys() method that may be familiar from other services.
We are working on formal documentation (which is why this isn’t flagged as “completed” yet), but some of the details are captured in this GitHub issue:

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

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…25 votesI 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

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

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…

Blob trigger support with Service Principle/Managed identity
We are trying to setup a Blob Triggered Function, but we have a limitation to use only Service principal/managed identity to access the storage because of the security concerns in directly using access keys.
We did not find a way to by-pass blob trigger to using connection string.
Theoretically, since Blob Storage is integrated with Azure Active Directory, it should be possible to provide the right RBAC permissions on my Blob Containers so that the Function's identity (Managed Service Identity)/Service principle has whatever permissions are necessary to create the trigger and read from the blobs.
We are expecting azure functions…
18 votesThis is something we are planning. Likely this would be accomplished through DefaultAzureCredential with the newest Storage SDKs, allowing more flexibility for local development.

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.
