Batch Consumption and Acknowledgment Modes
Learn to consume Kafka records in batches and choose the right acknowledgment mode to balance throughput, latency, and delivery guarantees.
Why Batch Consumption
By default a @KafkaListener processes one record at a time. For high-throughput pipelines, processing records in batches reduces overhead and lets you bulk-write to databases.
Enabling Batch Mode
Set batch-listener to true on the container factory, or configure it in properties.
