tMDMTriggerOutput
Receives an XML flow (Document type) from the preceding component in the Job.
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.
tMDMTriggerOutput receives an XML flow to set an MDM message so that MDM retrieves this message at runtime. With this component, you do not need to configure your Job any more in order to communicate the data changes from MDM to your Job.
This component works alongside the new trigger service and process plugin in MDM version 5.0 and higher. The MDM Jobs, triggers and processes developed in previous MDM versions remain supported. However, we recommend using this component when designing new MDM Jobs.
tMDMTriggerOutput Standard properties
These properties are used to configure tMDMTriggerOutput running in the Standard Job framework.
The Standard tMDMTriggerOutput component belongs to the Talend MDM family.
The component in this framework is available in all Talend products.
Basic settings
|
Property Type |
Either Built-in or Repository. |
|
|
Built-in: No property data stored centrally. tMDMTriggerOutput is expected to use this option in order to apply the default read-only schema. MDM_message is the only column of this schema. |
|
|
Repository: Select the repository file where properties are stored. The fields that follow are completed automatically using the fetched data. As tMDMTriggerOutput provides a fixed read-only schema, you are expected to use the Built-in option. |
|
Schema and Edit Schema |
A schema is a row description, it defines the number of fields that will be processed and passed on to the next component. The schema is either built-in or remote in the Repository. Click Edit schema to make changes to the schema. If the current schema is of the Repository type, three options are available:
|
|
|
Built-in: The schema will be created and stored for this component only. For more information about a component schema in its Basic settings tab, see Basic settings tab. This is the default option for tMDMTriggerOutput. With this option, the read-only schema is used to deal with the XML-format MDM message. |
|
|
Repository: The schema already exists and is stored in the repository. You can reuse it in various projects and jobs. For more information about a component schema in its Basic settings tab, see Basic settings tab. As tMDMTriggerOutput provides a fixed read-only schema, you are expected to use the Built-in option. |

tStatCatcher Statistics |
Select this check box to gather the processing metadata at the Job level as well as at each component level. |
Global Variables
|
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 more information about variables, see Using contexts and variables. |
Usage
|
Usage rule |
Use this component as an end component. It needs an input flow. To send message to MDM, you need to deploy the Job using this component on your Talend MDM Server and generate the corresponding trigger and process to invoke this Job in MDM. |
