# tMapRDBConfiguration

Stores connection information and credentials to be reused by other MapRDB components.

You configure the connection to a MapR-DB database in tMapRDBConfiguration and configure the other MapRDB components to reuse this configuration. At runtime, the Spark executors read this configuration in order to connect to MapR-DB.

This component is not shipped with your Talend Studio by default. You need to install it using the Feature Manager. For more information, see [Installing features using the Feature Manager](https://help.qlik.com/talend/r/en-US/8.0/studio-user-guide/install-features-to-talend-studio).
