We are rewriting Apache Kafka from scratch in Rust on top of Object Storage.
We have a novel approach to using Object Storage that keeps the low single digit latency of Apache Kafka while providing unlimited, on-demand, elastic throughput. Our system uses no disks in any part of the system. It doesn’t use any third-party component either. It maintains no distinction between data or metadata nodes.
We fully support all the new features introduced in Kafka 4.2, including modern consumer groups, share groups, and the new transaction V2 protocol.
We plan to release a production ready version in H1 2026. Both Serverless cloud and K8s deployable BYOC versions will be available in multiple regions on AWS and Azure on day one. Comparisons with Apache Kafka, AWS MSK, Confluent Warpstream, Redpanda will be posted at the time of release.
