trinodb / trino

Trino is a fast distributed SQL query engine for big data analytics. 
 See the User Manual for deployment instructions and end user documentation.
## Development
See DEVELOPMENT for information about development and release process,
code style and guidelines for implementors of Trino plugins.
See CONTRIBUTING for contribution requirements.
## Security
See the project security policy for
information about reporting vulnerabilities.
Trino supports reproducible builds as of version 449.
## Build requirements
* Mac OS X or Linux
 * Note that some npm packages used to build the web UI are only available
 for x86 architectures, so if you're building on Apple Silicon, you need
 to have Rosetta 2 installed.
* Java 25.0.1+, 64-bit
* Docker
 * Turn SELinux or other systems disabling write access to the local checkout
 off, to allow containers to mount parts of the Trino source tree
## 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 can easily 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 25 is selected (create one if none exist)
* In the Project section, ensure the Project language level is set to 25
### 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. The VM option generally required here
is `--add-modules jdk.incubator.vector`, but various `*QueryRunner` classes
might require additional options (if necessary, check the `air.test.jvm.additional-arguments`
property in the `pom.xml` file of the module from which the runner comes).
