Hey,
I'm facing a critical issue. I'm using flink 1.17.1. Flink Job has multiple sources
After adding logs and custom consumers everywhere, I figured out, that records go to both consumer A and consumer B.
Actually, I have more than 3 consumers, but here is an example:
Consumer A (topic A)
Consumer B (topic B)
Consumer C (topic C)
I found logs, that consumer B also tries to read topic A
and consumer C tries to read B
Here are my custom logs:
Wrong topic for consumer C B
Wrong topic for consumer B A
Interesting thing is that consumer A and consumer B also receives same data, as it should, so it's not simple re-routing.
Each consumer have separate kafka group.
Let me know which details I can provide? Thanks in advance
