Kyuubi, Release 1.7.0 Apache Kyuubi™ is a distributed and multi-tenant gateway to provide serverless SQL on Data Warehouses and Lake- houses. Kyuubi builds distributed SQL query engines on top of various kinds frameworks, e.g., Apache Spark, Flink, Doris, Hive, and Trino, etc, to query massive datasets distributed over fleets of machines from heteroge- neous data sources. The Kyuubi Server lane of the below ing. 2.2 Run Anywhere at Any Scale 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,
