Tflowtoiterate parallel execution issue

Bhaskar2 — Mon, 08 Mar 2021 11:32:53 GMT

I am reading the data from db table and giving it to the tflowtoiterate component and enabled the parallel execution (3 threads) option after tflowtoiterate component. for each row i am invoking one java function in tjavaflex component.

i just want to know that ,is there any probability that same record from db table gets assigned to multiple threads and java functions gets triggered for multiple times for the same records which should not happen.

this is very critical to me..please help me with your answers.

I also faced some similar issue, tJavaFlex run everytime with the same iteration.

So insteaf of tJavaFlex , i used tRunJob and then implement the login in the other child job.

My case was different but you can also try this

Thanks Prakhar for the reply.

Actually, in my case the same iteration is not running multiple times and in fact that will not happen. i have tried with multiples test cases.

My query is ,does talend assign same record to multiple threads in tflowtoiterate?
