Kafka Producer-Consumer Sequence with Offset Commit

A sequence diagram for a Kafka producer-consumer flow with offset commit, mapping how a Producer publishes a record to a Kafka Broker, how a Consumer Group polls and processes the returned batch, and how offsets are committed to an Offset Store with acknowledgment. It is used to clarify delivery and consumption order, support debugging of acknowledgment and offset handling, and help backend engineers, data platform teams, and architects design reliable event-driven systems.
