PartiQL Lang Kotlin

This is a Kotlin implementation of the PartiQL specification. PartiQL is based on SQL-92 and has added support for working with schemaless hierarchical data. PartiQL’s extensions to SQL are easy to understand, treat nested data as first class citizens and compose seamlessly with each other and SQL.

This repository contains an embeddable reference interpreter, test framework, and tests for PartiQL in Kotlin.

The easiest way to get started with PartiQL is to clone this repository locally, build, then run the REPL.

Status

PartiQL should be considered to be in "preview" status. It has been in use within a number of Amazon internal systems and an AWS product for over one year. The behavior of the language itself is mostly stable however the public API of the interpreter is slated to undergo significant improvements in the near term. (See the GitHub issues list for details.)

Using In Your Project

This project is published to Maven Central.

Group ID	Artifact ID	Recommended Version

}

Be sure to replace {version} with the desired version.

Building

To build this project, clone this repository and from its root directory execute:

$./gradlew build

This will build the reference interpreter and test framework, then run all unit and integration tests.

Building the documentation

Instructions on how to build PartiQL's documentation

Directory Structure

• docs/user documentation for developers embedding the interpreter in an application.
• docs/dev documentation for developers of the interpreter library.
• lang contains the source code of the library containing the interpreter.
• lang/jmh contains the JMH benchmarks for PartiQL.
• cli contains the source code of the command-line interface and interactive prompt. (CLI/REPL)
• testframework contains the source code of the integration test framework.
• integration-test/test-scripts contains the test scripts executed by the test framework as part of the Gradle build.
• integration-test/test-scripts-ignored contains test scripts which cannot be executed during the Gradle build.

Running JMH benchmarks

To run JMH benchmarks located in lang/jmh, build the entire project first and then run the following command:

$./gradlew jmh
