tParallelize Standard properties

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

The Standard tParallelize component belongs to the Orchestration family.

The component in this framework is available in all subscription-based Talend products.

Basic settings

Wait For

end of first subJob: sequence the relevant subJob to be executed at the end of the first subJob.


end of all subJobs: sequence the relevant subJob to be executed at the end of all subJobs.

Sleep Duration

Set the time interval in milliseconds between each check for subJob execution.

Die when one of parallelize subjobs fails

Select this option to have the Job quitting execution when any of the subJobs it executes fails.

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 rule

This component can be used as either a start or middle component in a main Job built of numerous subJobs. It can be connected to preceding or following components using OnSubjobOk, Parallelize or Synchronize links. You can use as many tParallelize components as you want in your master Job.

Note that this component is designed for Data Integration Jobs. Do not use it in the context of Data Services Jobs or Routes because it is not thread safe between parallel requests and will cause huge memory and CPU consumption. Use a Route if parallel processing is a requirement.


Outgoing links (from this component to another):

Trigger: Synchronize; Parallelize.

Incoming links (from one component to this one):

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

For further information regarding connections, see Using connections in a Job.
