Component family

Talend MDM



tMDMBulkLoad writes XML structured master data into the MDM hub in bulk mode.


This component uses bulk mode to write data so that big batches of data or data of high complexity can be quickly uploaded onto the MDM server.

Basic settings

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.

Since version 5.6, both the Built-In mode and the Repository mode are available in any of the Talend solutions.

Click Edit schema 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] window.

Click Sync columns to collect the schema from the previous component.



Built-in: You create the schema and store it locally for this component only. Related topic: see Talend Studio User Guide.



Repository: You have already created the schema and stored it in the Repository. You can reuse it in various projects and Job designs. Related topic: see Talend Studio User Guide.


XML field

Select the name of the column in which you want to write the XML data.



Type in the URL required to access the MDM server.


Username and Password

Type in the user authentication data for the MDM server.

To enter the password, click the [...] button next to the password field, and then in the pop-up dialog box enter the password between double quotes and click OK to save the settings.


Data Model

Type in the name of the data model against which the data to be written is validated.


Data Container

Type in the name of the data container where you want to write the master data.



Type in the name of the entity that holds the data record(s) you want to write.


Select Master or Staging to specify the database on which the action should be performed.



Select this check box to validate the data you want to write onto the MDM server against validation rules defined for the current data model.

Note that for the PROVISIONING Data Container, validation checks will always be performed on incoming records, regardless of whether or not this check box is selected.

For more information on how to set the validation rules, see Talend Studio User Guide.


If you need faster loading performance, do not select this check box.


Generate ID

Select this check box to generate an ID number for all of the data written.


If you need faster loading performance, do not select this check box.


Insert only

Select this check box to skip the step of checking whether the data records to be inserted already exist on the MDM server, thus achieving a better performance.

However, before using this option, you need to make sure that the data records do not exist in the database.


Commit size

Type in the row count of each batch to be written onto the MDM server.


Use Transaction

Select this check box then, in the Component List, click an existing connection component which will be used to commit the transaction.

Advanced settings

tStatCatcher Statistics

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


Outgoing links (from this component to another):

Row: Main,

Trigger: Run if; On Component Ok; On Component Error, On Subjob Ok, On Subjob Error.

Incoming links (from one component to this one):

Row: Main

Trigger: Run if, On Component Ok, On Component Error, On Subjob Ok, On Subjob Error

For further information regarding connections, 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.


This component needs always an incoming link to offer XML structured data. If your data offered is not yet in the XML structure, you need use components like tWriteXMLField to transform this data into the XML structure. For further information about tWriteXMLField, see tWriteXMLField.


If you are using a subscription-based version of the Studio, the activity of this component can be logged using the log4j feature. For more information on this feature, see Talend Studio User Guide.

For more information on the log4j logging levels, see the Apache documentation at
