Each instance of an event triggered function is backed by a single EventProcessorHost instance. The trigger (powered by Event Hubs) ensures that only one EventProcessorHostinstance can get a lease on a given partition. For example, consider an Event Hub as follows: 1. 10 partitions 2. 1,000 events distributed evenly across all partitions, with 100 messages in each partition When your function is first enabled, there is only one instance of the function. Let's call the first function instance Function_0. The Function_0 function has a single instance of EventProcessorHostthat holds a lease on all ten partitions. This instance is reading events from partitions 0-9. From this point forward, one of the following happens: 1. New function instances are not needed: Function_0 is able to process all 1,000 events before the Functions scaling logic take effect. In this case, all 1,000 messages are processed by Function_0. 2. An additional function instance is added: If the Functions scaling lo...
The following table explains the binding configuration properties that you set in the function.json file and the EventHubTriggerattribute. When you're developing locally, app settings go into the local.settings.json file.
The Event Hubs trigger provides several metadata properties. Metadata properties can be used as part of binding expressions in other bindings or as parameters in your code. The properties come from the EventDataclass. See code examplesthat use these properties earlier in this article.

To complete this tutorial, you need the following prerequisites: 1. Microsoft Visual Studio 2019. 2. Create an Event Hubs namespace and an event hub. The first step is to use the Azure portal to create a namespace of type Event Hubs, and obtain the management credentials your application needs to communicate with the event hub. To create a namespace and an event hub, follow the procedure in this article. Then, get the connection string for the event hub namespace by following instructions from the article: Get connection string. You use the connection string later in this tutorial.
This section shows you how to create a .NET Framework console application to send events to an event hub.
In this section, you write a .NET Framework console application that receives messages from an event hub using the Event Processor Host. The Event Processor Hostis a .NET class that simplifies receiving events from event hubs by managing persistent checkpoints and parallel receives from those event hubs. Using the Event Processor Host, you can split events across multiple receivers, even when hosted in different nodes.

There's an important distinction to note between services that deliver an event and services that deliver a message.
Event Grid is an eventing backplane that enables event-driven, reactive programming. It uses a publish-subscribe model. Publishers emit events, but have no expectation about which events are handled. Subscribers decide which events they want to handle.Event Grid is deeply integrated with Azure services and can be integrated with third-party services. It simplifies event consumption and lowers costs by eliminating the need for constant polling. Event Grid efficiently and reliably routes events...
In some cases, you use the services side by side to fulfill distinct roles. For example, an ecommerce site can use Service Bus to process the order, Event Hubs to capture site telemetry, and Event Grid to respond to events like an item was shipped.In other cases, you link them together to form an event and data pipeline. You use Event Grid to respond to events in the other services. For an example of using Event Grid with Event Hubs to migrate data to a data warehouse, see Stream big data int...

That depends on your performance requirements. I've been sending thousands of events one by one from a Logic App to an Event Hub (with some additional processing included), which took a maximum of maybe very few minutes. But whether this is good or bad is up to your use case. Also numbers maybe totally different for you.
