Component family

Talend MDM

 

Basic settings

Component List

Select the tMDMConnection component from the list if more than one connection is planned for the current Job.

Advanced settings

tStatCatcher Statistics

Select this check box to gather the processing metadata at the Job level as well as at each component level.

Dynamic settings

Click the [+] button to add a row in the table and fill the Code field with a context variable to choose your MDM server connection dynamically from multiple connections planned in your Job.

Once a dynamic parameter is defined, the Component List box in the Basic settings view becomes unusable.

For examples on using dynamic parameters, see Scenario 3: Reading data from MySQL databases through context-based dynamic connections and Scenario: Reading data from different MySQL databases using dynamically loaded connection parameters. For more information on Dynamic settings and context variables, see Talend Studio User Guide.

Global Variables

ERROR_MESSAGE: the error message generated by the component when an error occurs. This is an After variable and it returns a string. This variable functions only if the Die on error check box is cleared, if the component has this check box.

A Flow variable functions during the execution of a component while an After variable functions after the execution of the component.

To fill up a field or expression with a variable, press Ctrl + Space to access the variable list and choose the variable to use from it.

For further information about variables, see Talend Studio User Guide.

Usage

This component is to be used along with the tMDMConnection component.

Note that the tMDMCommit and tMDMRollback components also include an option in their Basic settings to explicitly close a connection.
