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.

Add binding to Key Vault
Functions often need password, API keys, and connection strings to connect to other services and retrieve data. It would be great if those secrets could easily be obtained from Key Vault.
354 votesHi all,
We’re pleased to announce a public preview of our Key Vault references feature, which you can learn more about here: https://azure.microsoft.com/en-us/blog/simplifying-security-for-serverless-and-web-apps-with-azure-functions-and-app-service/
There are some limitations to the initial preview, but we’re hoping to address those very soon. We’re looking forward to your feedback!
Thank you,

Enable dependency injection in C# Functions
It would be useful to have a form of DI in our C# Functions, so we can consistently inject things like our logger class, or other Autofac DI services, into every C# Function we create.
I'd like to create a SDK package which developers can import into their Function and get access to some common functionality via DI, to remove boilerplate redundancy.
Any solution for this kind of thing?
279 votesWe have started work to enable this. We discuss the approach and implementation some during our webcast last month at about minute 25 here: http://aka.ms/azurefunctionslive

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 ;-) )

Support for session-enabled Azure Service Bus queues/subscriptions
Currently the queue/subscription trigger only works with queues and subscriptions that does not use sessions (RequiresSession = false). It would be very useful if the runtime would detect that sessions are enabled and adapt accordingly. As far as I can see, the actual function code would not even have to be aware.
145 votesthis is being planned, will send a further update once it has started.
thanks

Enable custom 3rd party authentication providers
Outside of out of the box providers like facebook and google, provide samples and guidance on how to authenticate with others like LinkedIn.
128 votesWe’re moving this back to the unplanned status, as the started work was not completed, and we don’t have a current ETA.
We’ll update the status again once we have more information. This is still an item we’d like to do at some point.

Add TypeScript support to Azure Functions
Please support writing TypeScript in Azure Functions when you're creating Node functions

Add max calls/per day|hour|minute configuration for throttling
Now- any light ddos attack that Azure will not recognize- will affect me and my account. If I know that my service shouldn't receive more than 10000 calls per day, but I can't setup limits on incoming requests.
"Daily Usage Quota (GB-Sec)"- not bad idea, but it's something internal and synthetic for me. Call/per day- is much more native metrics for users.
62 votesthe current plan is to provide throttling controls on a per instance base, which would enable limiting the amount of executions. This can work for scenarios where downstream resources cannot be strained or even DOS attacks.
Thanks!

SQL Azure trigger support
Azure functions are great, but a lot of application logic is driven by data in SQL Azure DBs. It would be great to have a trigger based on a SQL Azure row data.
50 votesMoving this to unplanned to better reflect status. The previous update hasn’t changed, but since the work is on the Event Grid/SQL teams and we’re not planning on building a custom binding ourselves, this is unplanned.

Handle Storage Queue/Service Bus messages in batches
I want to be able to handle multiple messages per function call - we are using a third-party web service which works much more efficiently if the messages are passed to it in batches. I know we could use a timer to trigger the function and grab messages from the queue ourselves but if we do that the function won't scale out automatically.
41 votesNothing planned short term but a great ask. This is an item that could potentially be contributed if interest to do so earlier. Hoping we get this planned soon.

Trigger Azure Function From Table Storage
Allow create, update and delete on a table storage row to trigger an Azure Function.

Allow websockets ( SignalR ) feature in azure serverless using Functions
Currently Websockets ( SignalR ) like continuous stream feature is not possible with Azure server less, please add this feature so we can make more use of azure functions.
33 votesLooks like the community (more specifically Anthony Chu) has already taken a stab at this. Please see the following article (https://anthonychu.ca/post/cosmosdb-real-time-azure-functions-signalr-service/) and GitHub repo (https://github.com/Azure/azure-functions-signalrservice-extension) for details of his implementation.
Your feedback on whether this satisfies your scenarios would be appreciated.

Function App Service support for Azure B2C
If I build a web app using Azure B2C for authentication, I'd like to use it as the authentication provider for Azure Functions too. Although I can set up the same providers, using B2C would be cleaner and enable me to support users with local logins (traditional username and password) too.
26 votesThis item is planned for the next year.

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.
24 votesGreat request and have heard a bit on this over the last few weeks. Keep the votes coming

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.
22 votesWe’re looking at a lot of improvement around this experience. However, because of the nature of Functions (you control the code,) you will always need to be considerate of socket exhaustion.

Add support for Kafka Streams from HD Insight
Azure Functions should be able to be triggered from Apache Kafka. The triggered function should be able to be configured for a specific consumer group, with options to explicitly commit the consumer's offset.
Ideally Kafka Streams could be supported, with special support for local storage of KTables.
22 votesNo change, but moving this to unplanned to better reflect project status.

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…18 votesNo plans for this right now, but please keep the votes coming.

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)17 votesThis 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.

Support for Azure Alerts
Currently you can only configure Azure Alerts on the App Plan that is hosting your Azure Function. However, it would be great to do this on a Function level to detect failures and other metrics.

We have been working on this, and are a few months out from enabling it.

Azure Functions teamOriginal Update
This is partially supported today. You can click through to the App Service Settings blade and click on the graph that shows up there.
This lets you set up basic alerts on failure rates/etc or GB-sec thorughput.
We’re adding Application Insights integration soon and that will provide even more options for setting up more granular alerts: github.com/Azure/azure-webjobs-sdk-script/i..

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.16 votesWe agree this needs to happen and we’re figuring out the best path forward.
