Custom SQL Source

Connect Kotlin DataFrame to any JDBC-compatible database using a custom SQL source configuration. Easily integrate unsupported SQL databases in Kotlin DataFrame using a flexible custom source setup. Define a custom SQL source in Kotlin DataFrame to work with any JDBC-based database.

If your SQL database is not officially supported, you can either create an issue or define a simple, configurable custom SQL source.

See the How to Extend DataFrame Library for Custom SQL Database Support guide for detailed instructions and an example with HSQLDB.
