问题 I am already using an IoT Hub and have configured message routing to route TwinChangeEvents to an Event Hub. An Azure function with an EventHubTrigger processes the messages. This works perfectly fine. Now, I wanted to configure message routing to route DeviceLifecycleEvents to another Event Hub. Again, another Azure function with an EventHubTrigger should process the messages. However, the function is not triggered when I connect or disconnect devices. When I change the data source of the

问题 we need to setup 4 EventHub and 3 Azure Functions. So what is the best way to have high throughput and Scalable parameters that we can set to have a system that can handle 75k message/sec?

问题 I'm trying to debug an Azure Function locally. It's an EventHubTrigger. The problem is that I need to debug the code locally because I still don't have the "real" settings. My code currently looks like this: public static class Notificator { [FunctionName("Notificator")] public static async Task Run([EventHubTrigger("achievements")]UserAchivementNofication notification, ILogger log) { } } But when I try to debug it, I'm getting this error: Microsoft.Azure.WebJobs.Host: Error indexing method

问题 I have a Python program that generates streaming data. Each piece of data is stored as a variable called message . Since Event Hubs does not offer a Python SDK, I've opted to use their REST API. I've attempted to push the data to my Event Hub instance as a part of my Python program that generates data as follows: r = requests.post("https://{Instance name}.servicebus.windows.net/{Path}/messages", message) print(r.status_code, r.reason) Upon executing this code, I receive a 401 Unauthorized

问题 I am using eventhub for ingesting a lot of events. I have multiple consumers which are running behing a scaling group reading these events from the eventhub which has multiple partitions. I was going through the Azure SDK in python and was confused as to what to use. There is eventhubconsumerclient, eventprocessorHost .... I would like to use a library where my multiple consumer can connect using the consumer group, the partitions are assigned dynamically to each consumer and checkpointing is

问题 I am using below code receive the events from Azure Event-Hub https://docs.microsoft.com/en-us/azure/event-hubs/event-hubs-dotnet-framework-getstarted-send#receive-events I want to Handle the requests coming to event-hub Sequentially .
