Problems while reading data from kafka

[c4hm]

Hi,

I want to visualise kafka data with SP. While trying to connect to kafka I'm running into different problems:

1. in most of the cases the NEXT button (in the kafka adapter settings) is grey. After changing settings forth and back multiple times I can klick next (with the initial settings). I don't understand, why the button is grey (or black).
2. SP seems to forget the kafka password (every time I try to Edit adapater I have to reenter the password.
3. There is no way to configure a consumer group name. SP creates a consumer group KafkaExampleConsumer1726.... The number looks like a timestamp.
4. Even after creating a matching consumer group KafkaExampleConsumer... in kafka I don't see any data.
   Is there a more detailed documentation or how to for reading data from kafka? Are there any plans to add a consumer group field? Is there a way to activate more verbose logging (or even logging at all). The STDOUT from the containers/pods is not (helpful) enough.

Many thanks for your support.
