# tDynamoDBConfiguration properties for Apache Spark Streaming (deprecated)

Availability-note[Deprecated](https://help.talend.com/r/en-US/Cloud/labels-on-talend-help-center/availability-deprecated)

This content is deprecated.

These properties are used to configure tDynamoDBConfiguration running in the Spark Streaming Job framework.

Information noteDeprecation: Spark Streaming is deprecated beginning with the R2026-09 release. Use Spark Structured Streaming instead.

The Spark Streaming tDynamoDBConfiguration component belongs to the Storage and the Databases families.

This component is available in Talend Real-Time Big Data Platform and Talend Data Fabric.

## Basic settings

| Properties | Description |
| --- | --- |
| Access key | Enter the access<br>key ID that uniquely identifies an AWS Account. For further information about how to<br>get your Access Key and Secret Key, see [Getting Your AWS Access<br>Keys](http://docs.aws.amazon.com/ses/latest/DeveloperGuide/get-aws-keys.html). |
| Secret key | Enter the secret access key,<br>constituting the security credentials in combination with the access Key.<br><br>To enter the secret key, click the [...]<br>button next to the secret key field, and then in the pop-up dialog box enter the password<br>between double quotes and click OK to save the<br>settings. |
| Region | Specify the AWS region by selecting a region name from the list. For more information<br>about the AWS Region, see [Regions<br>and Endpoints](http://docs.aws.amazon.com/general/latest/gr/rande.html#s3_region). |
| Use End Point | Select this check box and in the field displayed, specify the Web service URL of the<br>DynamoDB database service. |

## Advanced settings

| --- | --- |
| Connection pool | In this area, you configure, for each Spark executor, the connection pool used to control<br>the number of connections that stay open simultaneously. The default values given to the<br>following connection pool parameters are good enough for most use cases.<br><br><ul> <li> <p> <span>Max total number of connections</span>: enter the maximum number            of connections (idle or active) that are allowed to stay open simultaneously.</p> <p>The default number is <em>8</em>. If you enter <em>-1</em>, you allow unlimited number of open connections at the same                time.</p> </li> <li> <p> <span>Max waiting time (ms)</span>: enter the maximum amount of time                    at the end of which the response to a demand for using a connection should be returned by                    the connection pool. By default, it is -1, that is to say, infinite.</p> </li> <li> <p> <span>Min number of idle connections</span>: enter the minimum number                        of idle connections (connections not used) maintained in the connection pool.</p> </li> <li> <p> <span>Max number of idle connections</span>: enter the maximum number                            of idle connections (connections not used) maintained in the connection pool.</p> </li> </ul> |
| Evict connections | Select this check box to define criteria to destroy connections in the connection pool. The<br>following fields are displayed once you have selected it.<br><br><ul> <li> <p> <span>Time between two eviction runs</span>: enter the time interval                                    (in milliseconds) at the end of which the component checks the status of the connections and                                    destroys the idle ones.</p> </li> <li> <p> <span>Min idle time for a connection to be eligible to                                            eviction</span>: enter the time interval (in milliseconds) at the end of which the idle                                        connections are destroyed.</p> </li> <li> <p> <span>Soft min idle time for a connection to be eligible to                                                eviction</span>: this parameter works the same way as <span>Min idle                                                    time for a connection to be eligible to eviction</span> but it keeps the minimum number                                            of idle connections, the number you define in the <span>Min number of idle                                                connections</span> field.</p> </li> </ul> |

## Usage

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