Ursa - a new Iceberg-first storage engine for Kafka
Summary
Ursa proposes a diskless storage engine for Kafka that stores topics in Iceberg/Delta Lake via object storage. It promises up to 10x lower infra costs, instant scale, easier rebalancing, and simpler ops, with adaptable topics in the same cluster. The project is not yet open-sourced and faces a competitive landscape among open-source and commercial Kafka ecosystems.
