Introduces Confluent Cloud Freight clusters, a new cluster type optimized for cost-effective, high-throughput, latency-insensitive workloads. Key technical advancements include autoscaling to optimize resource utilization, direct writes to object storage (e.g., S3) to bypass local storage and inter-AZ replication, and the use of Fetch From Follower to reduce cross-zone traffic costs. The post also highlights the integration with Private Networking Interface (PNI) for secure and cost-effective VPC interconnection. Freight clusters are built on the Kora engine and can scale from 2 to 152 eCKUs.
