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.

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.

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

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...

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.
"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…

We will update this item when there is a plan to implement it.

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();};

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.

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.
4 votesWe do plan to provide more control over scaling on an app level in the future – as the app is the unit of scale. As such will likely manifest as an app setting and not a function binding. Thanks for the feedback.

@EventhubOutPut supporting Partitionkey
Currently its not clear from the document whether @EventHubOutPut supports a partitionKey to write the events. There is no examples for java. Can the below document be updated ?

dynamic "newBatchThreshold" on queue triggered functions.
When i host a queue triggered azure function on an app service, i would like the ability to programatically alter "newBatchThreshold" for a queue triggered function at runtime.
So that when extraordinary conditions occur, i can decrease the number of messages causing stress on the system.I have many messages passing through a queue triggered function. Most of the time they are easy to process, so i have "newBatchThreshold" set to 64.
This normally causes 20-30% database load processing these messages.
We recently processed a batch of data where the messages all caused a substantially more complex than normal workflow…
2 votesThis is great feedback!
We have no immediate plans to implement this, but we do have plans to tweak the batching behavior in our triggers and I will update this item if it is easy to add this functionality at the same time.

Dynamic file names for Blob out bindings - Python
I am currently workig with an HTTP trigger with some paramateres. Based on those parameters I do some calculations and save results into a file on blob storage account. Currently I am saving them in static file name defined on binding but I woul dlike to be able to generate dynamically the file name in the az func code.
For example:
{
"type": "blob",
"direction": "out",
"name": "outputBlob",
"path": "container/{calculatedFileName}.csv",
"connection": "AzureWebJobsStorage"
}where calculatedFileName is something we define in the code.
Is that something feasible? I am using Python.
Thanks in advanced.

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'.
