### _Why are the changes needed?_ Apache Derby is no longer active. One major drawback of Derby is that it does not support multiple connections to single db files, making it hard to analyze the data on local development. SQLite may be the most popular embedded DBMS in the world. It lives almost in every smartphone (at least Android and iOS integrate SQLite), which means SQLite is quite stable and may be a good choice for standalone production deployment. SQLite provides a CLI command `sqlite3` which is easy to use to connect a data file and run queries. Multi connections to a single db file is allowed, which helps a lot to analyze the data when the Kyuubi server is running. ### _How was this patch tested?_ - [x] Add some test cases that check the changes thoroughly including negative and positive cases if possible - [ ] Add screenshots for manual tests if appropriate - [x] [Run test](https://kyuubi.readthedocs.io/en/master/develop_tools/testing.html#running-tests) locally before make a pull request Closes #4950 from pan3793/sqlite.
