# tDynamoDBConfiguration properties for Apache Spark Batch
These properties are used to configure tDynamoDBConfiguration running in the Spark Batch Job framework.

This component is not supported with Spark 4.0.x.
## Basic settings

role | Select this checkbox to leverage the instance profile credentials. These
credentials can be used on Amazon EC2 instances, and are delivered through the
Amazon EC2 metadata service. To use this option, your Job must be running within
Amazon EC2 or other services that can leverage IAM Roles for access to resources.

Applications Running on Amazon EC2 Instances](http://docs.aws.amazon.com/IAM/latest/UserGuide/id_roles_use_switch-role-ec2.html). |

key ID that uniquely identifies an AWS Account. For further information about how to
get your Access Key and Secret Key, see [Getting Your AWS Access

Information noteNote: This option is available when Use an existing
connection and Inherit credentials from AWS
role are cleared. |

constituting the security credentials in combination with the access Key.

## Usage
| Usage guidance | Description |
| --- | --- |
| **Usage rule** | This component is used with no need to be connected to other
components.
The configuration in a tDynamoDBConfiguration component
applies only on the DynamoDB related components in the same Job. In other words, the
DynamoDB components used in a child or a parent Job that is called via tRunJob cannot reuse this configuration.
This component, along with the Spark Batch component Palette it belongs to,
appears only when you are creating a Spark Batch Job.
Note that in this documentation, unless otherwise explicitly stated, a
scenario presents only Standard Jobs, that is to
say traditional
Talend
data integration Jobs. |
