Client Bidirectional Compatibility

The video tutorial introduces the concept of bidirectional compatibility in Kafka, a feature that allows different versions of Kafka clients and brokers to communicate effectively. This feature was introduced in Kafka version 0.10.2 in July 2017. The tutorial explains that older clients can interact with newer brokers and vice versa, emphasizing the importance of using the latest client library versions for better stability and features. It concludes with a recommendation for further reading on the Continent blog.
