AWS has announced the general availability of Provisioned Mode for Kafka Event Source Mappings (ESMs) with AWS Lambda, offering enhanced control and performance optimization for Kafka-based event-driven applications.

  • Allows fine-tuning of throughput by configuring minimum and maximum event pollers
  • Enables responsive auto-scaling between configured poller ranges
  • Simplifies networking by removing PrivateLink configuration requirements
  • Supports various Kafka platforms including Amazon MSK, Confluent, and Redpanda
  • Offers performance improvements up to 70% compared to on-demand mode

The new feature helps developers build more responsive and scalable event-driven applications by providing granular control over event processing resources and throughput.
