## What it is
Apache Kyuubi is a distributed, multi-tenant Thrift JDBC/ODBC gateway that provides serverless SQL access to data warehouses and lakehouses. It manages pre-warmed Spark, Flink, and Trino engine instances so end users and BI tools can run SQL against large-scale data without managing compute themselves.

## Use cases
- run interactive SQL queries on Spark from BI tools via JDBC
- provide a multi-tenant SQL gateway for a data lakehouse
- serve HiveServer2-compatible connections for big data analytics
- run large ETL batch jobs through a unified SQL interface
- isolate compute resources per user or tenant on a shared cluster
- query Iceberg, Hudi, Delta, and Hive tables from one endpoint

## When to choose
- you need a serverless, multi-tenant SQL entry point over Spark/Flink/Trino
- you want HiveServer2 compatibility so existing JDBC/ODBC clients and BI tools work unchanged
- you require per-user engine isolation, high availability, and high client concurrency
- you want unified authentication and authorization across multiple query engines

## When to avoid
- you need a lightweight embedded SQL engine rather than a distributed gateway service
- your workloads are small-scale single-user queries where a direct Spark or Trino connection suffices
- you need OLTP-style transactional queries against a relational database
- you cannot operate JVM-based server infrastructure or a Hadoop/lakehouse storage layer
