Definition
A group of consumers that work together to consume events from Kafka topics. Kafka ensures that each event within a partition is delivered to only one consumer within a group, enabling parallel processing and fault tolerance.
Why it matters (in Poovi’s context)
Consumer groups allow multiple instances of a service to process events in parallel, significantly increasing throughput and resilience.
