thank you for your kind reply

I found the issue, but this is a way to send person / car metadata from one source to different topics
What I want is a way to send each metadata to a different topic for 2 or more sources.

I want that issue’s solution. that issue is same as my problem

I want to know how to modify config file and deestream_test5_main.c

What do you mean send each metadata to a different topic for 2 or more sources?
one source metadata send to one topic?
another source metadata send to another topic? if we have two source.
