Apache Kafka Share Groups are NOT true queues. Here's why that's a good thing.

Apache Kafka's version 4.2 introduces the Share Group feature, often equated to a "Kafka queue," which offers elastic consumer scaling, individual message acknowledgments, and built-in "poison pill" handling, akin to traditional message brokers like RabbitMQ and ActiveMQ. Share Groups allow for faster consumption by relaxing strict ordering requirements, making them suitable for applications such as migrating legacy message queue systems, variable-latency task processing, and consumer cost-saving initiatives. While Share Groups enhance scalability and efficiency by allowing more reactive consumer scaling, they require a specific Java client to maintain application isolation and necessitate careful tuning of message distribution settings to optimize high-throughput environments. Monitoring lags and individual messages is crucial due to the relaxed order guarantees, with Kafka's built-in tools partially supporting this need. Overall, Share Groups offer a new trade-off between efficiency and order strictness, appealing to scenarios where strict sequential processing is not essential.
