# Thrift

HeavyDB uses [Apache Thrift](https://thrift.apache.org/) to generate client-side interfaces. Interface definitions can be found in the `$OMNISCI_PATH/omnisci.thrift` file.

Read the [Apache Thrift Documentation](https://thrift.apache.org/docs/) to learn how to use Thrift to generate client-side interfaces for different programming languages.

You can find sample client code examples in the `$HEAVYAI_PATH/samples` directory.
