An experiment to block access to brokers for consumers while producing records in the topic. The consumers should get back to consume when the kafka brokers are available again and the accumulated lag must be deal with quickly.

Verify that your application handles a change of the leader properly.

Motivation

By testing your system's resilience to Kafka leader changes in a partition, you can identify potential weaknesses and take appropriate measures to improve its performance.

Structure

To conduct this experiment, we will ensure that all Kafka topics and producers are ready and that the consumer receives and processes messages correctly. We will then elect a new leader for one partition in Kafka and expect the system to work fine.
