It is suitable for Most of the Kyuubi engine types have a distributed backend or can schedule distributed tasks at runtime. They can process data on single-node machines or clusters, such as YARN and Kubernetes. Besides State-of-the-art query engines • Multiple application for high throughput • Sharable execution runtime for low latency • Server-side global and continuous optimization • Auxiliary performance plugins
