AWS Lambda now supports queues for Apache Kafka in self-managed Kafka event sources

AWS Lambda now supports queues for Apache Kafka in self-managed Kafka event source mappings, enabling higher parallelism and throughput for event-driven workloads.

• Scale processing beyond partition count using Kafka share groups (Apache Kafka 4.2+)
• Multiple event pollers consume concurrently from same partition, each supporting up to 10 concurrent invocations
• Ideal for workloads like image/video encoding, fraud detection, and telemetry ingestion that prioritize speed over ordering
• Decouples parallelism from partition count with no producer or topic configuration changes
• Improves resilience by preventing slow/failed events from blocking others in same partition
• Available in all AWS commercial regions where self-managed Kafka ESM is supported

Queue mode enables higher throughput during traffic spikes and more resilient processing for Kafka workloads that don't require strict partition ordering.
