`ClearTimer`  <a name="cfn-iotevents-detectormodel-action-cleartimer"></a>
Information needed to clear the timer.  
*Required*: No  
*Type*: [ClearTimer](aws-properties-iotevents-detectormodel-cleartimer.md)  
*Update requires*: [No interruption](https://docs.aws.amazon.com/AWSCloudFormation/latest/UserGuide/using-cfn-updating-stacks-update-behaviors.html#update-no-interrupt)

`DynamoDB`  <a name="cfn-iotevents-detectormodel-action-dynamodb"></a>
Writes to the DynamoDB table that you created. The default action payload contains all attribute-value pairs that have the information about the detector model instance and the event that triggered the action. You can customize the [payload](https://docs.aws.amazon.com/iotevents/latest/apireference/API_Payload.html). One column of the DynamoDB table receives all attribute-value pairs in the payload that you specify. For more information, see [Actions](https://docs.aws.amazon.com/iotevents/latest/developerguide/iotevents-event-actions.html) in *AWS IoT Events Developer Guide*.
