# EventHubCheckpointer.Update(string, DateTime)

[Type overview](/orleans/docs/api/csharp/microsoft.orleans.streaming.eventhubs/orleans.streaming.eventhubs.eventhubcheckpointer/) | [Methods](/orleans/docs/api/csharp/microsoft.orleans.streaming.eventhubs/orleans.streaming.eventhubs.eventhubcheckpointer/methods/)

[Source](https://github.com/dotnet/orleans/blob/e4e752cedecc2976811db49802c7a999b1f1c704/src/Azure/Orleans.Streaming.EventHubs/Providers/Streams/EventHub/EventHubCheckpointer.cs#L134-L151)

```csharp
public void Update(string offset, DateTime utcNow)
```

Updates the checkpoint. This is a best effort. It does not always update the checkpoint. The latest offset is always tracked in memory so that [EventHubCheckpointer](/orleans/docs/api/csharp/microsoft.orleans.streaming.eventhubs/orleans.streaming.eventhubs.eventhubcheckpointer/) can persist it on shutdown.

### Parameters

- `offset` (`string`)
- `utcNow` (`DateTime`)
