# Java driver for Tarantool Cartridge
[](https://github.com/tarantool/cartridge-java/actions/workflows/tests-ce.yml)
[](https://github.com/tarantool/cartridge-java/actions/workflows/tests-ee.yml)
Java driver for Tarantool Cartridge for Tarantool versions 1.10+ based on the asynchronous
[Netty](https://netty.io) framework and official
[MessagePack](https://github.com/msgpack/msgpack-java) serializer.
Provides CRUD APIs for seamlessly working with standalone Tarantool
servers and clusters managed by [Tarantool Cartridge](https://github.com/tarantool/cartridge)
with sharding via [vshard](https://github.com/tarantool/vshard).
## Quickstart
Here is an easy way to try using Tarantool together with this Java driver.
Look at the [single instance test](/src/test/java/io/tarantool/driver/integration/SingleInstanceExampleIT.java) to start
experimenting with a single Tarantool server instance and a simple Java app.
You can set breakpoints and run it in "debug" mode using your IDE.
Testcontainers library will start a [single instance Tarantool server](src/test/resources/single-instance.lua) for you.
Try to manipulate data in Tarantool in real time through evaluating Java expressions in debug mode or using the Tarantool
console.
If you want to start a simple Tarantool application manually, all you need is to install Tarantool and run it with this file:
``` bash
tarantool src/test/resources/single-instance.lua
```
Example of creating a `TarantoolClient` instance:
https://github.com/tarantool/cartridge-java/blob/2f8e826deb9833a5deb6d21177527a46e8fdd039/src/test/java/io/tarantool/driver/integration/SingleInstanceExampleTest.java#L51-L59
Example of the `TarantoolClient` API usage:
https://github.com/tarantool/cartridge-java/blob/2f8e826deb9833a5deb6d21177527a46e8fdd039/src/test/java/io/tarantool/driver/integration/SingleInstanceExampleTest.java#L64-L79
If you use this code in another project don't forget to add a `cartridge-driver` dependency:
```xml
io.tarantool
cartridge-driver
0.14.0
```

## Requirements
Java 1.8 or higher is required for building and using this driver.
## Building
1. Docker accessible to the current user is required for running integration tests.
2. Set up the right user for running Tarantool with in the container:
```bash
export TARANTOOL_SERVER_USER=
export TARANTOOL_SERVER_GROUP=
```
Substitute the user and group in these commands with the user and group under which the tests will run.
3. Use `./mvnw verify` to run unit tests and `./mvnw test -Pintegration` to run integration tests.
4. Use `./mvnw install` for installing the artifact locally.
