# DeltaTimeSessionWindowConfigurationProperty

A structure that contains the configuration information of a delta time session window.

[`DeltaTime`](https://docs.aws.amazon.com/iotanalytics/latest/APIReference/API_DeltaTime.html) specifies a time interval. You can use `DeltaTime` to create dataset contents with data that has arrived in the data store since the last execution. For an example of `DeltaTime` , see [Creating a SQL dataset with a delta window (CLI)](https://docs.aws.amazon.com/iotanalytics/latest/userguide/automate-create-dataset.html#automate-example6) in the *ITA User Guide* .

## Example

// The code below shows an example of how to instantiate this type.
// The values are placeholders you should change.
import { aws_iotanalytics as iotanalytics } from 'aws-cdk-lib';
const deltaTimeSessionWindowConfigurationProperty: iotanalytics.CfnDataset.DeltaTimeSessionWindowConfigurationProperty = {
  timeoutInMinutes: 123,
};
```

## Properties

- `timeoutInMinutes`: number (required) — A time interval.

  You can use `timeoutInMinutes` so that ITA can batch up late data notifications that have been generated since the last execution. ITA sends one batch of notifications to Amazon CloudWatch Events at one time.
