I am going to use Azure IoT Hub for handling communication, but the next step is the problem. I want to store the telemetry to a database. This is where I get confused. Some examples says that I should use Azure BLOB storage or Azure Table storage or Azure SQL. After some years of data collection I want to start creating reports of the data. So the storage needs to be

Should the event hub have same number of partitions as throughput units?

不羁的心 提交于 2019-12-09 09:26:54
问题 For Azure event hub 1 though put unit equals 1MB/sec ingress. So it can take 1000 messages of 1 KB.

I am not sure about limitation on Event Hub partition, i read that it is also 1MB/sec. But then does that mean to use event hub effectively i need to have same number of partitions? 回答1: Great Qstn! Few Basics 1 ThruPut Unit (hereby, I will

How to go back to a checkpoint with Azure EventHub Trigger to Functions?

I have an EventHub trigger implemented with Azure Functions App. My business logic implementation was wrong in that function and had to correct it. I have corrected my implementation on Functions App, how would I change the checkpoint to that Azure Function to go back 24 hours and make the stream data available to Functions App? When I needed to start processing of events in a Hub from scratch, I went to Blob Storage -> azure-webjobs-hosts container and deleted the blobs with names like yournamespace.servicebus.windows.net/yourhub/$Default/X . Those blobs store the current checkpoints, so if

问题 We're new to the Azure messaging service and Functions, we learned the basic concept of different message service like Storage Queue, Service Bus Queue, Service Bus Topic and Event Hubs we also read the fan-out pattern by microsoft but that works more like fan-out then fan-back, which means during the fan-out process, current function still hold up there until all resource fan-back. A simple scenario would be, we are saving an object in azure function starter and after saved successfully into
