 ## What is Kyuubi?
 
-Kyuubi is a distributed multi-tenant Thrift JDBC/ODBC server for large-scale data management, processing, and analytics, built on top of Apache Spark and designed to support more engines (i.e., Flink). It has been open-sourced by NetEase since 2018. We are aiming to make Kyuubi an "out-of-the-box" tool for data warehouses and data lakes.

+SQL on data warehouses and lakehouses.
 
 Kyuubi provides a pure SQL gateway through Thrift JDBC/ODBC interface for end-users to manipulate large-scale data with pre-programmed and extensible Spark SQL engines. This "out-of-the-box" model minimizes the barriers and costs for end-users to use Spark at the client side. At the server-side, Kyuubi server and engines' multi-tenant architecture provides the administrators a way to achieve computing resource isolation, data security, high availability, high client concurrency, etc.
