tMDMTriggerOutput – Docs for ESB 7.x


Receives an XML flow (Document type) from the preceding component in the

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

Basic settings

Property Type

Either Built-in or Repository.


Built-in: No property data stored

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

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
to make changes to the schema. If the current schema is of the Repository type, three options are available:

  • View schema: choose this
    option to view the schema only.

  • Change to built-in property:
    choose this option to change the schema to Built-in for local changes.

  • Update repository connection:
    choose this option to change the schema stored in the repository and decide whether
    to propagate the changes to all the Jobs upon completion. If you just want to
    propagate the changes to the current Job, you can select No upon completion and choose this schema metadata
    again in the Repository Content


Built-in: The schema will be
created and stored for this component only. Related Topic: see

Talend Studio User

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. Related Topic: see
Talend Studio User Guide

As tMDMTriggerOutput provides a
fixed read-only schema, you are expected to use the Built-in option.

Advanced settings

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 +
to access the variable list and choose the variable to use from it.

For further information about variables, see
Talend Studio

User Guide.


Usage rule

Use this component as an end component. It needs an input

To send message to MDM, you need to deploy the Job using this
component on your MDM server and generate the corresponding trigger
and process to invoke this Job in MDM.

For further information about how to deploy a Job onto MDM server
and how to generate a trigger or a process, see
