How to parallelize subjobs on Open Studio

Alpha549 — Mon, 07 Mar 2022 20:25:56 GMT

Hello everyone,

I would like to parallelize subjobs with Talend Open Studio.

I tried to use several On Component Ok links, but there is an order, and a following link doesn't start if the previous is not executed...

Thank you 🙂

Hello

Open the Job settings viewer, click Extra panel, then select 'Multil thread execution' box, this option allows different subjobs to run parallelly. Note that, there is no trigger link between subjobs. eg:

subjob1

subjob2

subjob3

Hello shong,

thank you for your answer.

Here I would like to parallelize only specific subjobs. The other ones are executed one after the other as normal behavior.

Is it possible ?

Hello,

If you have a request that need parallelize only specific subjobs, tParallelize could achieve your goal and it also allows you to synchronizes the execution of a subjob with other sub-jobs within the main Job.

tParallelize is available in all subscription-based Talend products not open source.

Best regards

Sabrina

@Alpha549 Alpha549 , with open studio, move these specific subjobs to child job and enable parallel execution in child job, run the subjobs in order in main job. eg:

subJob1

|onsubjobok

tRunJob1

|onsubjobok

subJob2
