When you want the function to process a single event, the Event Hubs trigger can bind to the following types:
| Type | Description |
|---|---|
string |
The event as a string. Use when the event is simple text. |
byte[] |
The bytes of the event. |
| JSON serializable types | When an event contains JSON data, Functions tries to deserialize the JSON data into a plain-old CLR object (POCO) type. |
| Azure.Messaging.EventHubs.EventData1 | The event object. If you are migrating from any older versions of the Event Hubs SDKs, note that this version drops support for the legacy Body type in favor of EventBody. |
When you want the function to process a batch of events, the Event Hubs trigger can bind to the following types:
| Type | Description |
|---|---|
string[] |
An array of events from the batch, as strings. Each entry represents one event. |
EventData[] 1 |
An array of events from the batch, as instances of Azure.Messaging.EventHubs.EventData. Each entry represents one event. |
T[] where T is a JSON serializable type1 |
An array of events from the batch, as instances of a custom POCO type. Each entry represents one event. |
1 To use these types, you need to reference Microsoft.Azure.Functions.Worker.Extensions.EventHubs 5.5.0 or later and the common dependencies for SDK type bindings.
