What are the enhanced features of the Streaming service?
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.
