Vectorized executor and hybrid row/column-based storage engine 6. Workload management 7. Reliable transaction processing 8. Online scale-out

The use of continuous query language (CQL) accelerates service development, enables tasks to be easily submitted to the Streaming platform for real-time processing, facilitates output of results, and allows tasks to be terminated at the appropriate time. Additionally, access control is implemented based on user types. As a result, only the user who creates the topology can view and manage the topology, preventing unauthorized operations. The Nimbus HA mechanism enhances cluster availability.
