Leaderless Architecture
Ursa's unique leaderless design removes inter-AZ data transfer. No more complex leader elections or high-overhead data replication across availability zones. Lower network costs mean a leaner and more fault-tolerant data streaming platform.
Lakehouse-Native Storage
Rather than replicate data multiple times on expensive disks, Ursa shifts to affordable object storage with open standard formats. You pay pennies for storage while retaining enterprise-grade durability and performance.
Stateless Brokers
Scale compute power instantly—and independently of storage—so you never overprovision resources. Pay only for the throughput you truly need, right when you need it.
Stream-Table Duality
Ursa connects to data lakehouses directly, reducing integration complexity and eliminating the patchwork of Kafka connectors. Streamlined data flows mean faster, simpler, and cheaper operations.
No inter-AZ data transfer.
Minimal overhead, simpler networking.
No inter-AZ client-to-broker communication.
Reduced latency and cross-region data transfer.
Open table formats
(e.g., Iceberg, Delta)
Zero-copy streaming
from Kafka to Lakehouse
Effortless topic-to-table conversion.
Unify streaming and batch with a single copy of data.
Compute and storage decoupled.
Scale each independently.
No overprovisioning.
Pay only for what you use.
Auto-scaling
on demand.
