Question - Why is only Consumer's session timed out? about rust-rdkafka

[HalsekiRaika]

I was able to solve the problem myself.

I'll try to summarize what I did because maybe some of you are the same person.

• Adjust the worker_threads of the #[tokio::main(flavor = "multi_thread", worker_threads = 2)]
• This was used to solve the Session Timeout caused by the stuck thread doing the Poll in the StreamConsumer. I don't know the criteria as I haven't looked into the details, but in my case I confirmed that it fired perfectly at about 2.
• Set auto.offset.reset to Consumer.
• In my case, this has been the best solution. I don't know why, but when I created a new group using auto.create.topics.enable=true, etc. and connected a Consumer, the Offset was set to Invalid and the default auto.offset.reset=latest was used. (Perhaps this is the intended behavior.)

It was an inexperienced and content-lacking solution, but I hope it will help someone.
