How to fire and forget a job

subbu_kobra — Wed, 11 Mar 2026 04:48:47 GMT

Hi,

I am new to Talend. I have requirement to fire and forget a job from another ETL job.

I have a parent job and a Child job. From Parent ETL job I need to invoke child ETL job but should not wait until child job is completed, I need to proceed with next the steps in parent job.

I have tried using tRunjob component by setting “Use independent process” flag to true but did not work out. Parent job is still waiting until child job is completed. I have tried tsystem component as well but no luck.

I am sure this is not something unique requirement. Can someone help with step by step approach on how to achieve this?

Thanks,
Bala

Hi @subbu_kobra

Have you tried using a tParallelize component? This way, you can run your child job in parallel with the rest of your parent job at the same time.

If you are planning to run the parent job from the Talend Management Console, this is probably a bad idea. The Talend management console is there to kick off jobs (scheduled triggers, manual execution, or webhook triggered) on remote servers and monitor their execution flow, reporting issues, providing logs and metrics, etc.

If you are running the parent job from a windows scheduler or windows batch script/program then you can have the parent Talend job do stuff and then call a system command to execute a windows batch script/program and in that windows batch script/program you can use the START command to launch another independent batch script/program, which will run as a separate program. Inside that independent batch script/program can be commands to run a Talend job or whatever you want. It will of course run unmonitored by anything but the Windows system, so you will need to craft the job to handle any error situations you care about.
