[baumeister25]

A tryout mechanism for the retry logic of spring kafka should be implemented:
IDEA: use a REST-endpoint to set a flag that makes all kafka request fail

@baumeister25
Mechanism works. But use case is missing.

found a use case example for retry. Implemented and it works as expected. However, codes optimization (clean code) is advised. Discuss with Fabian for feedback.

Retry has been implemented and tested by Kafka team. It works as expected.

The implemented Retry mechanism can be tested and observed in devon4j-kafka-ship-sample repo: https://github.com/devonfw-forge/devon4j-kafka-ship-sample
