using tKafkaInput : do i always need tFixedFlowinput?

android1686764069 — Fri, 15 Nov 2024 21:24:09 GMT

hello

In my project, we use Kafka, and I jave to read some json messages.

This is what I have:

Connection is OK and I read the messages with the tKafkaInput component. however, I can't process the data, they are not displayed with the tlogRow component.

If I try this with a flowtoIterate, then I can process the data, for example they are displayed with the tlogRow component.

Do I have to use fFlowToIterate whenever I want to use tKafkaInput?

Thank you

Hi @android devops

You don't need tFlowToIterate+tFixedFlowInput components, what's the output type? Can you check the flow statistics via GUI? How many rows are processed?

Regards

my screeshot comes from a child job.

I have to run the parent job, but I don't know how I can have access to the number of lines processed in the child job....

Anyway, as I dais in my 1st message, if I remove the tFlowToIterate+tFixedFlowInput components, I can't see the messages...
