trino

Connecting C++ and Trino with ADBC

Instructions

Tip

If you already have a Trino instance running, skip the steps to run Trino in a Docker container.

Prerequisites

1. Install Pixi

2. Install dbc

3. Install Docker

Set up Trino

1. Start Trino in a Docker container:

   docker run -d --rm --name trino -p 8080:8080 trinodb/trino

Connect to Trino

1. Install the Trino ADBC driver:

   dbc install --level user trino

2. Customize the C++ program main.cpp as needed,

   • Change the connection arguments in the AdbcDatabaseSetOption() calls
     • Format the URI according to the DSN (Data Source Name) format used by the Trino Go client, or keep it as is to use the TPC-H data included in the Trino Docker container image
   • If you changed which Trino instance you're connecting to, also change the SQL SELECT statement in AdbcStatementSetSqlQuery()

3. Build and run the C++ program:

   Using Make:

   pixi run make
   ./trino_demo

   Or using CMake:

   pixi run cmake -B build
   pixi run cmake --build build
   ./build/trino_demo

Clean up

1. Clean build artifacts:

   Using Make:

   pixi run make clean

   Using CMake:

   rm -rf build

2. Stop and remove the Docker container running Trino:

   docker stop trino
   docker rm trino
