Queue Storage Concurrency

[rbx44]

Hi,

I am having problem with Function app version : 2.
I am using Functions with Cognitive services. In version 1 I was able to set the max concurrency for Queue by setting BatchSize = 1 in Host.json file. This works as long as I don't make 10 calls/per second.

I recently upgraded to version 2.0 and I can't find batchSize under extensions -> queues anymore.

Now

Any possible solutions?

Those properties are still present and configurable. The "queues" section just moved under "extensions" - all the options should be the same.

The sample host.json shown in https://github.com/Azure/azure-functions-host/wiki/host.json-(v2) is not intended to show all options, as the v1 version did. This is confusing and we'll find a way to fix this

I have tried that and it doesn't seem to be working.

With batchSize property under extensions -> queues. @mathewc This is the error I am getting

Works fine if I take batchSize out or set it to 2. I want to set it to 1

I can't see what values you're setting for batchSize/maxDequeueCount in the image above. However, I think you're running into a bug that we just fixed in Azure/azure-webjobs-sdk@246f634 (@paulbatum). We're rolling a release out now with this fix.

I am setting it to 1. That would do it. Thanks!!
