How to run same job with multiple times in parallel in Talend Open Source Studio

Anonymous — Thu, 27 Sep 2018 15:13:40 GMT

Hi All,

I am using Talend Open SOurce Studio. And i have a use case like as - I want to execute same job multiple times with different WHERE condition and this has to be parallel execution. I've used multi thread option of tRunJob but i am not getting desired outcome.

It means how to get different values for same dynamically. If i am using context then it would be same for all threads.

Please provide me appropriate solution.

Thanks in advance

calling a subjob, you can set context variable of the subjob.

here is the documentation with samle:

in our case you fave to create a job retrieving where clause (sample: read from a file ) in row link add flow to iterate them iterate to trunJab.
this job get context from the previous one and run a query adding the where close.
