Build requirements

  • Mac OS X or Linux
  • Java 11.0.7+, 64-bit
  • Docker

Building Trino

Trino is a standard Maven project. Simply run the following command from the project root directory:

./mvnw clean install -DskipTests

On the first build, Maven downloads all the dependencies from the internet and caches them in the local repository (~/.m2/repository), which can take a while, depending on your connection speed. Subsequent builds are faster.

Trino has a comprehensive set of tests that take a considerable amount of time to run, and are thus disabled by the above command. These tests are run by the CI system when you submit a pull request. We recommend only running tests locally for the areas of code that you change.

Running Trino in your IDE

Overview

After building Trino for the first time, you can load the project into your IDE and run the server. We recommend using IntelliJ IDEA. Because Trino is a standard Maven project, you easily can import it into your IDE. In IntelliJ, choose Open Project from the Quick Start box or choose Open from the File menu and select the root pom.xml file.

After opening the project in IntelliJ, double check that the Java SDK is properly configured for the project:

  • Open the File menu and select Project Structure
  • In the SDKs section, ensure that JDK 11 is selected (create one if none exist)
  • In the Project section, ensure the Project language level is set to 11

Running a testing server

The simplest way to run Trino for development is to run the TpchQueryRunner class. It will start a development version of the server that is configured with the TPCH connector. You can then use the CLI to execute queries against this server. Many other connectors have their own *QueryRunner class that you can use when working on a specific connector.

Running the full server

Trino comes with sample configuration that should work out-of-the-box for development. Use the following options to create a run configuration:

  • Main Class: io.trino.server.TrinoServer
  • VM Options: -ea -Dconfig=etc/config.properties -Dlog.levels-file=etc/log.properties -Djdk.attach.allowAttachSelf=true
  • Working directory: $MODULE_DIR$
  • Use classpath of module: trino-server-main

The working directory should be the trino-server-main subdirectory. In IntelliJ, using $MODULE_DIR$ accomplishes this automatically.

Running the CLI

Start the CLI to connect to the server and run SQL queries:

client/trino-cli/target/trino-cli-*-executable.jar

Run a query to see the nodes in the cluster:

SELECT * FROM system.runtime.nodes;

Run a query against the TPCH connector:

SELECT * FROM tpch.tiny.region;
