cMap Standard properties

These properties are used to configure cMap running in the Standard Job framework.

The Standard cMap component belongs to the Transformation family.

The component in this framework is available in Talend Data Management Platform, Talend Big Data Platform, Talend Real Time Big Data Platform, Talend Data Services Platform, and in Talend Data Fabric.

Basic settings

Open Map Editor	Click the [...] button to open the map specified in the Map Path in the Mapping perspective.
Map Path	Specifies the map to be executed. Click the [...] button next to the Map Path field to open a dialog box in which you can select the map you want to use, then click the [...] button next to Open Map Editor to work with the map selected. Note that this map must have previously been created in the Mapping perspective.
Output Type	From the drop-down list, select how you want the output to be written. Default: The default output is the same as the input, or Java if the map outputs Java. String: Use this option if the data in the output column is to be a String. Byte Array: Use this option if the data in the output column is to be a Byte array. InputStream: Use this option if you are working with Talend Data Mapper metadata and the input is a stream.

Advanced settings

Exception Threshold	Talend Data Mapper returns an execution status with an severity value which can be OK, Info, Warning, Error or Fatal. By setting the exception threshold, you can specify the severity level at which an exception is thrown, thus enabling downstream components to detect the error in cases other than the default value of Fatal. From the drop-down list, select the severity level at which an exception may be thrown during the execution of a map. Fatal (default): An exception is thrown when a fatal error occurs. Error: An exception is thrown when an error (or higher) occurs. Warning: An exception is thrown when a warning (or higher) occurs.

Usage

Usage rule	cMap is used for Routes that require data mapping.
Limitation	Due to license incompatibility, one or more JARs required to use this component are not provided. You can install the missing JARs for this particular component by clicking the Install button on the Component tab view. You can also find out and add all missing JARs easily on the Modules tab in the Integration perspective of your studio. For details, see Installing external modules. You can find more details about how to install external modules in Talend Help Center (https://help.talend.com). This limitation applies to maps that reference databases.

Note:

For further information about performing transformations using Talend Data Mapper , see Talend Data Mapper User Guide.
When using representations other than Map, CSV, Avro, XML, and Cobol, running this component with the old Eclipse-based Runtime may create temporary folders, which are not automatically removed after stopping the Runtime. If you frequently run Talend Data Mapper, these files may pile up and eventually lead to a disk full error. When the error occurs, the runtime fails. To avoid this, ensure that you perform periodical cleaning. For more information, see Cleaning up temporary folders and files.
